The difference between castable refractory and ramming mass/refractory cement

Castable refractory is a kind of refractory material made of granular and powder material, and add a certain amount of binder and moisture together.It has high fluidity, suitable to use castable method construction, no heating can harden unshaped refractory material.The aggregate, powder, binder, additive composition, water or other liquid materials. In general use site casting, casting and tamping vibration method, and also can be made into the preform.

Castable refractory mainly by porosity, binder, aggregate varieties classification:
1, according to the porosity distribution by dense refractory castable and porosity of not less than 45% of the insulation refractory material of two kinds;
2, according to the binding agent has a combination of water, chemical bonding, cohesion and refractory castable:
1) combined with water hardening at room temperature hardening and hardening by hydration, the main varieties are Portland cement, ordinary calcium aluminate cement, pure calcium aluminate cement, fused pure calcium aluminate cement castables, etc.;
2 chemical combination of castables at room temperature generally by adding hardening agent to form a chemical reaction to harden, the main varieties are water glass, aluminum sulfate, phosphate castable, etc.;
3) condensed aggregate combined with castable was hardened by sintering during calcination, and the main varieties were made from clay castables.

Refractory castable is one of the most widely used unshaped refractories.
Mainly used to build a variety of heating furnace lining, such as the overall structure of pressure in metallurgy, petroleum, chemical, building materials, electricity, machinery industrial furnaces and heating equipment heavy tube rice use,High quality castable can also be used for smelting furnace, refractory castables generally have high room temperature strength, can be made of prefabricated parts in the furnace site installation.

Ramming mass/refractory cement is refers to the ramming method/refractory cement construction, and under above normal temperature heating function hardening unshaped refractory material.Due to a certain gradation of refractory aggregate, powder, binder, admixture water or other liquid after mixing.According to the material by high alumina, clay, magnesite, dolomite, zirconium and silicon carbide carbon refractory ramming mass/refractory cement.

Ramming mass/refractory cement with silicon carbide, graphite, electric calcined anthracite as raw materials, mixed with a variety of ultra-fine powder additives, fused cement or composite resin as binder made of bulk material.To fill the gap or stack cooling equipment and masonry masonry with leveling layer filling material.Ramming mass/refractory cement chemical stability, erosion resistance, wear resistance, spalling resistance, thermal shock, widely used in metallurgy, building materials, non-ferrous metal smelting, chemical, machinery and other manufacturing industries!
Acid, neutral, alkaline ramming material/refractory cement widely used in Coreless intermediate frequency furnace, core induction furnace.As medium frequency furnace ramming material/refractory cement used to melt gray cast iron, ductile iron.Can be calcined iron, vermicular cast iron and cast iron melting alloy, carbon steel, alloy steel, high manganese steel, tool steel, heat-resistant steel, stainless steel, aluminum and its alloy melting, melting of copper, brass, copper and bronze and copper alloy etc.

Taurus Refractory ramming mass Factory mainly engaged in professional manufacturer of development, production and sales of the refractory mixture such as melting copper, aluminum and zinc furnace lining. And supply castable refractory for copper smelting, ramming mass for molten copper,fire clay,refractory mortar, refractory cement ,refractory mixture, refractory concrete and silica sand for copper smelting.
