Diversified Development of Refractory Raw Materials Adapts to the New Normal of Steel Industry
Refractory material is the basic material of steel industry. Materials industry and steel industry promote each other and develop together. As our economy enters a new normal, a series of new features have emerged in the iron and steel industry: Overcapacity, declining profitability, increased environmental and resource constraints, and more challenges for transformation and upgrading. The new normal of steel industry puts forward new requirements, new thinking and new changes to the refractory industry at the upstream of the industrial chain. The performance and application of refractories have shown features of characterization, diversification, refinement, efficiency, and low consumption in recent years, to which the development of refractory raw materials must adapt and will also evolve towards new trends such as diversification, enrichment, and specialization.

Why Do External Thermal Insulation Materials Always Cause Fires?
At present, the building external wall insulation material is one of the important items for sampling interior finish materials, which is closely related to their frequent occurrence of fire accidents. For example, the fire in CCTV building originated from the use of non-flammable organic insulation materials. These materials produce a large amount of smoke and toxic gases due to incomplete combustion and pyrolysis during fires, and most people in fire accidents may suffocate by inhaling these smoke and toxic gases. Therefore, the fire risk caused by building external wall insulation material is very high, which is easy to cause major casualties. And based on work experience, the author discusses the causes for the fire and preventive measures. Firstly, the industry standards are not sound, and the product quality is uneven. At present, the production and use of external insulation materials are chaotic. And the organic insulation materials currently used in the building field mainly include polystyrene board (EPS), extruded polystyrene board (XPS), and polyurethane (PU), whose greatest strengths are that they are lightweight, good in insulation and thermal insulation. And their biggest weaknesses include poor fire safety, easy aging and flammable. The first two are widely used due to their low prices, while the latter is slightly superior in terms of thermal conductivity, construction performance, and combustion performance. The industry standards for external insulation materials are not yet sound, and some manufacturers have loopholes in management. The external insulation materials produced cannot meet the design requirements of building fire protection, and the fire resistance grade and limit cannot meet the national standards. After the product is put on the market, congenital safety risks are posed for building fire accidents. Secondly, the construction cycle is long and there are numerous hidden dangers at the construction site. For the construction industry, energy conservation and insulation is the national policy, and wall insulation is an important means to realize building energy conservation, thus building insulation materials are widely used. In reality, the construction period of high-rise buildings, large-scale stadiums and other buildings is generally two to three years, during which various construction processes alternate with each other and are inconvenient to manage. Some management personnel neglect the investigation and rectification of on-site fire hazards and the setting of temporary fire water, and focus all their energy on catching up with the construction period and squeezing costs.

Tips for Selecting High-quality and Inexpensive Refractory Bricks
1. To inquire about the price of refractory bricks, it is necessary to explain the material of the required refractory bricks to the manufacturer by telephone or fax. Generally, refractory bricks are mainly divided into: high aluminum refractory brick, clay refractory brick, lightweight refractory brick, magnesium-chromium brick, fusion cast brick, and silicon brick.
