Q: Is fireclay poisonous?: Refractory materials are typically oxides, alumina, magnesium oxide and aluminate cement and etc, which are non-toxic.

Q: What are the basic requirements of continuous casting for molten steel? What are the requirements for refractory materials?: Refractories for continuous casting is an important part of the continuous casting machine, in addition to the characteristics of general refractory material, also for the purification of molten steel and improve the steel quality, stable molten steel temperature and composition, control and regulate the flow of the molten steel and other functions, so it is called functional refractories. The above is provided by the China Technology Department

Q: What do we mean by saying that a ladle cover knots, elbow knots, blowpipe knots in refractory materials? What is the “knot”?: A less accurate view of the statement is probably the meaning of the “construction of refractory material" , for example, pouring castable can be called “knot”, the pounding of the construction can also be said that, so it is with spraying paint.

Q: who knows the uses of refratories?: 1. Category: chinalco refractory aggregate Al2O3 containing about 35% -40%, high-alumina refractory aggregate containing 55% Al2O3. Widely used in thermal equipment, high-temperature furnace wall, heatable brick bed, chimneys, lining and other basic construction, it is mainly used in military, warehouse, air defense, industrial and mining enterprises, and general industrial furnace, the finest raw materials in cement admixture and expanding agent plant. Having a low density, thermal conductivity, water absorption, fire-resistant thermal insulation properties. Lightweight mullite refractory aggregate: This project uses natural materials to synthesize advanced refractory raw materials. It is a new synthetic materials. lightweight refractory aggregate to make lightweight refractory castables at high temperature has been in short supply. In most cases it is replaced by used light weight brick pieces. the entailing problem is : high-temperature lightweight castable refractory shrinks at high temperatures, affecting the performance of high-temperature lightweight castable refractory. high alumina refractory aggregate is often used.

Q: How to choose thermal insulation materials for flood heating?: 1, Select the appropriate floor material suitable for radiant floor heating. The floor radiant heating system mainly transfer heat through the ground concrete and the ground material to the room. Therefore in the heating season the ground material will always be heated during heating season. Therefore, it is better to choose stone materials and compround floor plate insensitive to tenmperature change with good heat dissipation and functions. Currently, wood floor is not suitable for the ground radiant heating system. 2, choose the pipe with anti permeability performance. Plastic floor heating pipe itself has a certain air permeability, if oxygen penetrates in it is prone to oxygen erosion and system's mental device will be eroded, resulting in the risk of leakage. Therefore in order to ensure the reliable operation of the heating system, the selected pipe must have anti oxygen permeation performance, and meet the standard stipulated by the DIN4726 oxygen permeation quantity: and be less than 0.1mg\L.d at 40 C.

Q: Who knows what kind of fire prevention materials are there?: 1, Fire-proof board Fire-proof board is the most frequently used materials in the market. There are two kinds of fireproof boards which are commonly used; one is the high pressure decorative board, which has the advantages of fire prevention, damp proof, abrasion resistance, oil resistance, easy cleaning, and more variety of colors and designs. The other one is a glass magnesium fire board, the outer layer of which is a decorative material, the inner layer of which is a mineral glass magnesium fire material. It can resist 1500-degrees high temperature, but not suit for decoration. The installation of fireproof ceiling in the exit passageway, stair well and corridor can ensure safety evacuation, and protect people from the spread of the fire. 2 Fire-proof door Fireproof door is divided into wooden fire proof door, steel fire proof door and stainless steel fire proof door. Usually the fire proof door is used for the opening of the firewall, the entrance to the staircase, the evacuation of the aisle, the openings of the pipeline and other parts of the building, and it has an important role in fire separation and reducing the loss from fire. 2 Fire resisting shutter I hope it may be helpful to you.

Q: Please answer the questions about the packing and transportation requirements of refractory materials.. Requirements for packing of refractory bricks: Bricks are usually made from pallets.Generally take the automotive, coastal sea city.

Q: What are first rate fire resistant window materials?: class A window not less than 1.2 hours, class B window not less than 0.9 hours, Class C window not less than 0.6 hours. technical requirments: 1, materials and accessories (1) the window frame is made with a certain strength sufficient to safeguard the integrity and stability of the steel frame or wooden frame. (2) steel frame and mound layer can choose the galvanized steel plate or stainless steel plate. Its selection standards is in line with GB12955 "Steel Fireproof Door General Technical Condition" provisions of Article 5.1. (3) wood frame and mound layer material selected from the standard should be consistent with GB14101 "General Technical Conditions of Wooden Fireproof Door" in the provisions of Article 5.1.1. (4 ) steel, wood frame the inside filler material should be incombustible material. (5) fireproofing glass can be used without affecting the fire windows fire resistance test approved product. light transmittance of glass should not less than 75% of commom sheet glass which is the same number of layers. ( 6) a sealing material between the frame and the fire-resistant glass flame retardant materials should be used, which can play the role of fireproofing and smoke insulation in case of fire (7) hardware fitting should be tested as approved supporting product

Q: Development trend of refractory industry: China announced that from 2004 January, the export of most refractory raw materials will be cancelled, and the export of finished products will also reduce the tax rebate rate. This means that important raw materials for further export restrictions, some developed countries dependent on imports of China's refractory materials and products of the refractories industry will have a major impact. In order to reduce costs, they will move their factories to Chinese, which is the development of Chinese refractories industry will also be an important opportunity. In addition, the convenience of communication and transportation, the change of the international market and the increase of e-commerce have also brought good opportunities to the development of refractory industry.
