Don't finalize the design - four seasons fire refractory castable

Number of visits: Date:8/11/2016

  Divided into the stereotypes refractories and refractory not stereotypes refractories. Don't finalize the design usually refers to refractory castable, is by a variety of aggregate or aggregate of one or more sticky and agent and mixed powder material, must be with one or more of the liquid mix, strong liquidity and plasticity.

  Pouring material is a kind of granular and powdered materials made of refractory material, and adding a certain amount of binder and water together. It has high liquidity, appropriate construction with casting method, without heating and hardening of monolithic refractories. By refractory aggregate, powder, binder and additive, water or other liquid materials. General in using on-site pouring, vibration or tamping method of casting forming, also can be made into bricks.

  Refractory castable is the production and the most widely used a monolithic refractories. It is mainly used for building various kinds of reheating furnace lining structure as a whole. Some high quality varieties can also be used for smelting furnace. Such as aluminate cement refractory castable can be widely used in all kinds of heating furnace and other slag, acid and alkali erosion of thermal equipment. In the molten iron, molten steel and slag erosion and working temperature and higher positions, such as the steel tank, ladle and blast furnace body, the tapping ditch, etc., can be used by the low calcium and pure alumina cement by sintering of good quality with high alumina and granular and powdered materials made of refractory castable. Again, such as phosphate refractory castable can be widely used in heating furnace and heating metal in soaking pit, also can be used in the coke oven, direct contact with the material in the cement kiln sites. In direct contact with molten slag and molten metal metallurgical furnace and some parts of the other container, using high-quality phosphate refractory castable for repair also has a good effect. In some working temperature is not very high and need to wear a higher position, the use of phosphate refractory castable is more appropriate. If choose just the jade made refractory castable refractory materials, under the reducing atmosphere using generally have better effect.

  As the ratio of monolithic refractories in refractory, refractory castable is bound to develop rapidly, at the same time varieties increase quality will also increase, the key still will develop low cement, ultra-low cement and without cement refractory castable, combining resource conditions homogenization and high-quality raw materials to improve the basic and special aggregate composition, research and promotion of using fiber reinforced refractory castable and their refractory castable, apply various additive to improve the performance of refractory castable, in addition, the development of special casting material (such as iron groove, ladle lining, etc.) as well as with special functional materials (such as abrasion resistance, acid, alkali resistance, high strength, heat insulation, with high strength and high thermal conductivity and other properties), improve the production equipment in production and application technology and construction of form a complete set of machines.

  To figure custom get samples free of charge Zhengzhou, the four seasons of fire resistant material co., LTD. Provide and all kinds of refractory refractory customized processing services

  Refractory bricks is made up of refractory aggregate, powder, binder, additives, water or other liquid made from carefully, by casting method into fixed shape of monolithic refractories. According to the binder is divided into refractory cement combining, phosphate, sodium silicate combining with and without cement, etc. According to the material can be divided into high aluminum, just the quality of the jade, clay, mullite stone, etc.

  The product can be arbitrary prefabricated into various shapes, good thermal shock resistance, high strength, good resistance to spalling. No juncture, good air tightness, less heat loss, energy saving; Can quickly repair kiln, improve furnace operation efficiency; Can realize direct hoisting mechanization construction, construction efficiency is high. Can solve the technical problems in the process of furnace building for the user; And can according to user requirements and the conditions of furnace type, for users to consider the lining design and various construction schemes.

  Refractory bricks is an important variety of refractory material and its proportion is more and more high. Refractory bricks is the high temperature furnace with construction area divided into small pieces, in advance and design a special shape, according to the shape production mould, pouring refractory castable, such as prediction in the factory after the forming, maintenance, bake to the site hangs used after assembling.

  In cement industry, casting with its castable irreplaceable advantages, and gradually in the cement kiln key parts (such as: grate cooler ha-ha, three times the wind valve, preheater smoke chamber) of the popularized gradually, has been more and more cement manufacturers began to accept and adopt casting solution, and show more excellent performance in use, and refractory material for cement manufacturers have brought good economic benefit.

  With the increase in the varieties of fabrication, common including the tapping ditch casting blast furnace, ladle cover fabrication, ladle vent brick, block and impact plate, casting ladle bottom, tundish slag dam, impact plate, the heating furnace with burners, car frame, and so on.
