With the continuous development of smelting steel around the world, the demand for lining materials has been rising year by year, and how to select the lining materials with high furnace age and low price has become the focus of customer attention.

Some manufacturers, in the purchase of lining materials, blindly pursue the price, in the purchase of lining materials, only look at the price per ton, will only use low-cost materials, because of the short age of the furnace only frequent ramming lining, and even more every day in repeated ramming lining, both waste of manpower, energy, capital, and virtually increase the comprehensive production cost, in view of the above situation, through the list analysis and comparison, Jincheng lining manufacturers, improve awareness to change the old concept. Charge selection should pay attention to its performance, otherwise the cheap price in the early stage is a great waste of cost in the later stage.

In the selection of lining materials, we must see the selection of materials, additives, ** and other information, and to choose a regular manufacturer, all kiln industry all the charges are imported technology, ****, a large number of old customers are an important reference for you to buy lining charges, good reputation and a large number of dealers, making my factory lining charges sales continue to double, The workers are working overtime every day to ensure the smooth progress of the sales.

According to the different needs of customers, the selection of refractory materials is also different, mainly divided into the following refractories: Acid refractory acid lining material, the use of high purity microcrystalline quartz sand, powder, adding high temperature sintering agent and mineralizing agent mixed into the dry vibration material, strictly control the particle size and the amount of sintering agent added, so regardless of the use of various knotting methods can obtain dense lining. Acid, neutral and basic refractory materials are widely used in coreless medium frequency furnace and cored induction furnace, and are used as refractory materials to melt gray cast iron, ductile cast iron, malleable cast iron, vermicular cast iron and cast iron alloys, and to melt carbon steel, alloy steel and high manganese steel.

The selection of furnace lining refractories must have the following characteristics:

1. At sufficient temperature, no deformation, no melting performance

2. Can have the necessary structural strength at high temperatures, and does not produce softening deformation

3. It must be stable in volume at high temperatures, and does not cause cracks due to expansion and contraction

4. When the temperature changes sharply or the heat is not uniform, it will not crack and flake

5. It can resist the chemical erosion of metal solution, slag and gas
