Mould fluxes is a kind of refractory material that is put on the molten steel level to be thermal insulation,anti oxidation and absorption of non-metallic inclusions in the process of continuous casting. The basic function of mould fluxes: Protecting the mould steel liquid from the two oxidation of air; Having good spreadability and insulation performance, prevent molten steel solidification or crus; Well absorbing the floating non metallic inclusion;Controlling the speed and uniformity of heat transmission from billet to crystallizer to reduce the thermal stress; Having good lubrication function for billet. The product of our company is designed and produced according to parameter of continuous caster and detailed production situation, which has good melting property and steady quality, and is suitable for different casting conditions. It can ensure the clean and smooth surface of casting block, and also can ensue that there is no shell and flux strip in mold, with even whip mark an without defect on he surface of casting block.There have many kinds of refractory products in our factory.Such as fire brick ,refractory raw materials ,refractory nozzle .When you want to know more kinds of refractory products ,welcome to view our website to know more.

1. The choice of kiln lining material? (1) Insulation, furnace shell and the permanent layer refractory insulation layer can choose between aluminum silica refractory fiber felt layer on the inner wall of the furnace shell, then clay fire brick masonry. Heat preservation brick can be single or double layer adopted according to the thickness of the lining design.? (2) The permanent layer and working layer: permanent layer typically USES clay brick masonry. Working layer is according to the size of the kiln, can use different materials such as clay, high aluminum, magnesium, aluminum, magnesium chrome brick, etc. We are in big volume of lime kiln adopts thermal stability good burn into basic brick, in a small volume of kiln, the use of the burning and not burn comprehensive basic brick masonry.? 2. Kiln lining building design? The design of the kiln lining to the heat preservation performance is good, heat storage principle. Kiln wall thickness is 600 ~ 850 mm, small volume lower limit, big volume to take close to upper limit. Kiln wall thickness, heat preservation performance is poor, high heat loss, energy consumption is high. General lime kiln wall structure since the furnace shell, in turn, is 40 ~ 70 mm fiber felt, 115 ~ 265 mm light clay brick, fire brick for sale , 230 mm, 230 mm layer brick work.

Changxing Refractory is a Chinese leading refractory and oil fracturing proppant manufacturer & supplier with a wide range industries in high temperature field . From a refractory bricks manufacturing factory, Changxing has become a professional manufacturer with various refractory materials and fire brick both in domestic and international market during 30+ years, whose customers covers North America, Middle East, Asia, Africa, etc. 1. Reduction in physical properties – Improper water content leads to a reduction in the physical properties associated with a monolithic refractory material. This can decrease the lifespan of the refractories as well as create issues for the end user throughout the time period in which they are in use. In many cases, end users select more costly refractories in order to acquire higher quality materials. The improper addition of water can completely negate this additional spend. In many cases leading to performance, that is inferior to properly mixed lower quality materials. 2. Increased set-up time – Materials in which too much water has been added will not set-up at the rate which they were designed to. In some cases, they may not set-up at all and may remain soft, spongey, or grainy. This may lead to the need to remove and re-cast the materials causing long and expensive delays. Furthermore, the rate at which monolithic refractories cure has an impact on the physical properties achieved. Accelerating and decelerating this reaction can have negative implications. There are ways to insure that materials are properly mixed. These methods include adequate training of the workforce, proper communication, have the mixing and use instructions available during an installation, have proper measuring devices available, and the use of mixing logs and even third party inspectors.Changxing has a production line, which is base on oil & gas applied ceramic proppant, and also with 3 factories focusing on all kinds of refractory materials used for iron & steel casting, cement,fire bricks glass petrochemical and ceramics industries. With abundant sources and professional techniques, Changxing Refractory would like to build a reliable and efficient platform for customers all over the world.
Regardless of the installation method being deployed in order to successfully install refractory materials, generally speaking, monolithic refractory installations share one common step, the addition of water. Whether the water is added in a large paddle mixer prior to being vibration cast, pumped, or shot-creted, at a nozzle prior to being gunned, or in a pail prior to being hand cast, this step has wide-ranging impacts on several aspects of the end result.Would you like to know more kinds of refractory products?welcome to come to our factory to view more refractory products. There have many refractory products in our website.such as :metal mixer refractory,ladle nozzle well block etc. The water content can easily be taken for granted. At times, it is tempting to add additional water relative to what is called for on a product’s mixing and use instructions in order to get the material to flow better, avoid voids, or extend the workability time. At other times, it can be seen as beneficial to reduce the water content with the intention of improving physical properties or expediting set times. While, the introduction of additional water is a far more common offense, in reality, introducing water to a refractory mix that is outside the parameters set by the material manufacturer can have the following detrimental impacts on the finished products: Dry-out – Improper mixing of monolithic refractories can cause significant problems during the refractory dry-out process. More water leaving the lining can lead to excess steam and pressure causing linings to crack, spall, or even explode during the dry-out. Furthermore, since the materials were improperly mixed in the first place, the physical properties associated with the material are likely reduced which compounds the problems potentially experienced during the dry-out period.

Based on silicon oxide (quartz powder, diatomaceous earth etc.), calcium oxide (also use slaked lime, carbide slag etc.) and reinforcing fibers (such as asbestos, glass fibers etc.), through mixing, heating, molding, autoclave curing, drying and other processes, calcium silicate insulation material is made to be a new type of insulation material. There has four kinds different types: 1. Asbestos calcium silicate: Its reinforced fiber is asbestos fiber.? 2. Non-asbestos calcium silicate: Its main performances are good thermal conductivity, high mechanical strength and linear shrinkage etc., better than asbestos calcium silicate. It is good to reduce the loss of construction and installation.? 3. Lightweight calcium silicate: Its thermal conductivity, flexural strength and other properties are better than asbestos calcium silicate, in particular for 50% light density, available temperature also increase from 650 ℃ to 1000 ℃.? 4. High-strength calcium silicate: It is made by hydration reaction between siliceous material and calcareous material, Tuobei Mullite stone as the main crystalline material. With adding adhesive and reinforcing material, its strength will be improved. The source:http://www.chinafirebrick.com/Company_News_79.html
