Q:How are qualitative and qualitative refractories understood?
Shaped refractory products, such as fired brick, fused brick (Rong Zhuzhuan), refractory insulation bricks, as well as experimental and industrial crucibles, utensils and other special products.
Q:What is the face brick
According to the shape and size can be divided into ordinary brick, standard brick, etc. can be used as a specific type of building furnace and various thermal equipment of high temperature building materials and structural materials, and at high temperature can withstand all kinds of physical and chemical changes and mechanical action.
Q:What is the weight of the refractory bricks?
Referred to as refractory brick. Refractory made from refractory clay or other refractory material. Light yellow or brownish. The utility model is mainly used for laying smelting furnaces, and can withstand high temperature between 1580 DEG C and 1770 DEG C. Also called brick. Refractory material of a certain shape and size. According to the preparation process can be divided into bricks, brick, electric melting brick (Rong Zhuzhuan), the refractory insulating bricks; according to the shape and size can be divided into standard brick, brick, brick and other specific type. It can be used as high temperature building materials and structural materials for construction kilns and various thermal equipments, and can undergo various physical, chemical and mechanical changes at high temperature. For example, refractory clay brick, high alumina brick, brick, brick etc..
Q:Can the fire clay to be reused?
According to the preparation process can be divided into bricks, brick, electric melting brick (Rong Zhuzhuan), the refractory insulating bricks; according to the shape and size can be divided into standard brick, ordinary brick, specific rotation. It can be used as high temperature building materials and structural materials for construction kilns and various thermal equipments, and can undergo various physical, chemical and mechanical changes at high temperature.
Q:What are kiln bricks?
Referred to as refractory brick. Refractory made from refractory clay or other refractory material. Light yellow or brownish. The utility model is mainly used for laying smelting furnaces, and can withstand high temperature between 1580 DEG C and 1770 DEG C. Also called brick. Refractory material of a certain shape and size. According to the preparation process can be divided into bricks, brick, electric melting brick (Rong Zhuzhuan), the refractory insulating bricks; according to the shape and size can be divided into standard brick, brick, brick and other specific type. It can be used as high temperature building materials and structural materials for construction kilns and various thermal equipments, and can undergo various physical, chemical and mechanical changes at high temperature. For example, refractory clay brick, high alumina brick, brick, brick etc..
Q:What is brick power, half brick power and full brick power difference?
All brick power up to 500 watts up and down. The internal circuit is tight and heating, the device has good adhesion, the circuit is more advanced, and the efficiency is high, so it can achieve small size and high power.
Q:Just what is in the furnace material?
Also called brick. Refractory material of a certain shape and size. According to the preparation process can be divided into bricks, brick, electric melting brick (Rong Zhuzhuan), the refractory insulating bricks; according to the shape and size can be divided into standard brick, brick, brick and other specific type.
Q:What are the categories of brick?
In a proper ratio of lime sand brick and quartz sand, sand or fine sand, the ground, Kazumi Wa, semi dry pressing and autoclaved curing and. The fly ash brick is made of fly ash as main raw material and mixed with cement material such as coal gangue, stone powder or clay. It is made up of batching, molding, drying and roasting. It can make full use of industrial waste residue and save fuel.
Q:What are the forming methods of refractory materials?
Basically there are three kinds: grouting molding, casting molding, machine forming, the three methods are applicable to different types of refractory materials, grouting molding for unshaped refractory
Q:What are the main constituents of refractory brick?
According to the composition of refractory bricks, they can be divided into five major categories, namely, silicon aluminum refractory bricks, basic series refractory bricks, carbon containing refractory bricks, zirconium containing refractory bricks and insulating refractory bricks. Any furnace is not made of only one kind of refractory brick, and it needs different fire bricks to match with each other. The following five categories of refractory bricks are described in detail.
