FAQ

Q2: What`s the lead time for my order?

A2: It depends on customers’ requirements and our production schedule. And usually we need 30-60 days for refractory bricks, 10-25 days for unshaped refractory materials and 10-20 days for ceramic fiber blankets.

 

Q3: Can you offer Door-to-Door delivery?

A3: Yes, but only for some countries such as U.S., UAE, Saudi Arabia, Iran, and Russia, etc.

 

Q4: What is the minimum quantity?

A4: There is no minimum order quantity. Depending on the item and processing, there may be a minimum production required, however we can offer a quotation based only on the quantity you need.

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 material is good for refractory brick?
No definite answer can be given, because any furnace is not made of only one refractory brick and needs a different fire brick to be used with each other.
Q:Outside wall tile (whole body smooth surface has small hole split brick) has cement pollution, with what product cleaning (cement, mortar, cleaning agent)?
Tile has a long period of cement pollution, a variety of weak acid cleaning can be removed, such as oxalic acid, acetic acid and so on, of course, the use of special cleaning agent is perfect. But the cost is higher.
Q:How are qualitative and qualitative refractories understood?
Unshaped refractory products, referred to as bulk loading, are made at the place of use for the required shapes and for heat treatment, such as castable, ramming, projection, spray, refractory clay, etc..
Q:Zirconium corundum 25 content or 40 content, how to distinguish in appearance?
Fused zirconia corundum brick is also called AZS AZS English is abbreviated to AZS, is based on three chemical composition of Al2O3 - Zr02 - Sio2 phase diagram of three component system, according to the content of the order, Al2O3 A, Zr02 Z, Sio2 S, national standards for the use of this abbreviation, such as No. 33 cast brick, abbreviated as AZS, 33#, No. 36 fused zirconium corundum brick, abbreviated as AZS, 36#, No. 41 fused zirconium corundum brick, abbreviated as AZS - 41#.
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 is brick power, half brick power and full brick power difference?
Power module. Small size, high power. General use should order additional storage energy, heat dissipation, etc.. Dimensions such as brick, so called brick power supply. Half brick power supply is half the size of all brick power supply.
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:Just what is in the furnace material?
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 are the categories of brick?
Ordinary brick size of 240 mm * 115 mm * 53 mm, according to compressive strength (Newton / square millimeter, N / mm2) size is divided into MU30, MU25, MU20, MU15, MU10, MU7.5, these intensity levels. Clay brick materials, cheap, durable, and fire prevention, heat insulation, sound insulation, moisture absorption and other advantages, is widely used in civil engineering. Waste brick can also be used as aggregate of concrete. In order to improve the shortcomings of ordinary clay bricks, such as small, self important and waste of soil, they are developing in the direction of light weight, high strength, hollow and big blocks.
