Q:What defect does fused cast refractories have ?
The impact on the quality of glass is mainly the defects that eroded down refractory materials mixed in the glass, thus being prodeced of grass products. Defects are mainly foreign body defects such as sand, knot and wave reinforcement.
Q:What are the disadvantages of the refractory industry?
The rapid development of continuous casting technology allows Hua Heng refractories to be improved in variety and quality. The development of refractory for continuous casting has a significant impact on the production of continuous casting and quality of continuous casting billet. Constructing and putting Baosteel into action has greatly pushed the improvement of the refractory technology. Continuous casting refractory is an important part of the continuous casting machine. In addition to the general characteristics of refractories, it is also required functions that can purify molten steel, improve the quality of steel, stabilize temperature and composition of the molten steel, control and regulate the molten steel flow. Therefore, it is known as functional refractories. Continuous casting Refractories include: (1) ladle refractory - ladle lining, permanent lining and ventilation components; (2) tundish refractories - permanent lining, coating, insulating plates, clad etc; (3 ) functional refractories - long nozzle for non-oxidizing casting, submerged nozzle, monolithic stopper, sliding gate; (4) ceramic purifier for purifying molten , slag dam, alkaline paint and horizontal separating ring and gate board for continuous casting.
Q:What brands are the best in the A-level refractory materials?
1 International (It is a well-known brand in the field of global boats and protective coatings, the products are famous for its safety, strength and smoothness, Akzo Nobel (China) Investment Co., Ltd.) 2 LANLING (It is a high-tech enterprise, and a large provider of industrial coatings, started in 1980, as well as a famous brand of Jiangsu Province, Jiangsu Lanling Chemical Group Co., Ltd.) 3 Champion (It is a high-tech enterprise who is involved in developing a number of industry standards, it is a industry-leading brand brand of Jiangsu Province Jiangsu champion coating Technology Group Limited)
Q:what is the common materials for home fireproofing material?
1, lumber core 2,decoration panel 3 , plywood 4 density board 5,chipboard 6 fireproof panel, 7.gypsum board Hope to adopt my opinion
Q:How is the fire endurance of the fireproof paint?
Fireproof endurance. fire resistance test of certain building components showed by standard time temperature curve from starting of fire to lose the supporting capabilities or its integrity or fireproof property. The fire proof endurance is 5hours.
Q:What are the fire resistances of grc partition panels?
A-level fireproofing which can last for 4 hours.
Q:What's the A grade fireproofing material?
Main materials are steel, wood, steel and wood. Fire door is one of the measures for buildings fire separation, and it is generally installed at the firewalls, entrances and exits of stairwells or tube well openings, which is required to play the role of fire protection and smoke control. Fire door plays an important role in preventing the spread of smoke and fire and reducing damages, so it must be strictly required. Fire dooor is classified into three classes of A, B, C, and their fire insulation and fire integrity is greater than or equal to the following values: A class fire door: 1.5h; B class fire door: 1.0h; C class fire door: 0.5h. It is in accordance with the provisions of 4.5.1.2 Article in GB12955-2008 "New Standard of Fire Doors".
Q:what grades are fire resistance of fireproofing glass divided into?
According to the fire resistance levels, it can be divided into three categories: Class A, it's a kind of fireproofing glass that can satisfy the requirements of refractory integrity, refractory and thermal insulation at the same time. This kind of glass has the properities of transmittance,fireproofing(smoke insulation, fire resistance, and keeping out thermal radiation), sound insulation, shock resistance. Class B, it's a kind of fireproofing glass that can satisfy the requirements of refractory integrity, refractory and thermal insulation at the same time. Such kind of fireproofing glasses mostly are composite fireproofing glasses and has characteristics of transmittance,fireproofing and smoke insulation. Class C, it's a kind of fireproofing glass that only satisfies the requirements of refractory integrity. This kind of glass has characteristics of transmittance, fireproofing, smoke insulation and high strength,etc.
Q:What is special refractories?
Long nozzle, slidding plate, tapping hole, stopper rods, and products that steel mills use
Q:For refractory, what is critical particle size? Thank you.
It also refers to the largest particle size of aggregate!
