09 Cu steel special CCM mold protect slag
Product description
In order to improve the quality of the rare earth processing, and realize the rare earth processing with mould steel slag toro rosso, localization of the protection work, I companies developed LF-type 4 rare earth steel slag series special, and wuhan iron and steel companies and research experiment, and achieved satisfactory results. Experiments prove LF-type 4 rare earth steel slag series special protection melting characteristics is better, fluid slag layer thickness can be stable in 10 ~ 13 mm, tons of consumption 0.75 kg, in use process without slag, the bond, "article mass and" cold steel phenomenon, casting surface quality is good, can satisfy the present rare earth processing of steel casting production requirements.

- Q: I wanna ask you, which level is b1 fireproof and thermal inuslation matertial ??
- What you said is the pixel! Only that has b1b2. Level b1 is the fireproofing level b1, because the particle does not belong to the fireproofing material. Only can fire?retardant. The wholesale of all kinds of thermal insulation material and construction need to look at the name.
- Q: What is fireproofing material? Are fireproof materials the same thing with thermal insulation materials and refractories?
- Insulation materials. Thermal insulation material is characterized by thermal insulation, which is one of the four traditional inorganic nonmetallic materials. Fire?retardant material is cahracterized by heat-resistant. Refractory is a kind of materials of resisit high temperature. Fireproof material, which is different from thermal insulation material and refractory, is a synthetic material with some fireproof subtrate added. It is essentially resistant to high temperature.
- Q: Who knows about the grade C fireproof door materials?
- I am happy to answer your questions. Wood or steel materials are usually used. The new national standard fire doors: According to the enacted GB12955-2008, the fire endurance of grade C fire doors is 0.5 hours and that of grade A and B are 1.5 hours and 1.0 hours respectively. I hope my answer can help you.
- Q: Which kind of external wall fire barrier zone material is better?
- The following types are: rock wool, aerated concrete, phenolic aldehyde and foam cement rock wool fire barrier zone "rock wool board" mainly uses water-repelling rock wool board produced by pendulum method as thermal insulation layer materia, and connecting and fixing base wall by binding and nail bonding, it is composed level A non-combustible building energy efficiency thermal insulation system by plastering layer composed by plastering mortar and glass?fiber mesh and decorative mortar finishing layer or coating. Good air permeability
- Q: Is aluminium oxide refractory material?
- Aluminium oxide with 2030?C melting?point is a kind of good refractory material. It can be used as analytical reagent, dehydration and adsorbing?material of organic solvent, catalyst of organic reaction, abraser,polishing agent, raw material of aluminum smelting technology and refractory material. Hope it is helpful to you.
- Q: What are fire?ratings of wall thermal insulation material?
- External wall thermal insulation materials are divided into A and B according to combustion level. Grade A is incombustible?material, while grade B is combustible?material. A few years ago, fires in CCTV building and Shenyang hotel resulted from grade B material. Currently grade A is usually used, and some are even cheaper than the grade B material. Grade A is roughly divided into insulation mortar, phenolic board, rock wool board, foam cement board, etc. Insulation mortar is quite good. It is easy and convenient to construct, has low cost, but the production is too simple and it is easy to fake. It is recommend to find a large manufacturer with complete formalities, such as provincal records of production, provincal records of use, city records, type test report at or above the provincial level, national fireproof report and design drawing collection of department of construction. Lack of any is unsafe. It is recommended to use mortar from Hebei Qizheng Haocheng New Building Material Co., Ltd. It is absolutely large manufacturer. MPC thermal?mortar produced by it is recommend product of Department of Construction in Hebei Province! Generally speaking, the combustion of phenolic aldehyde is grade B, but it can barely reach A2 when a thin layer of mortar is wiped outside.
- 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: What's the material of fireproof and wear-resisting floor?
- It is the kind of special concrete floor, and it should prevent from crash for it will produce fire by friction. It is mostly used for the warehouses storing explosive and inflammable objects and chemical materials. And its production process is the same with that of the common concrete floor, but it uses different material which needs to be the pebbles and sand after processing with marbles and dolomite.
- Q: how to classify the fireproofing material levels A1 A2 B1?
- their classification is shown specifically in Fireproof? Specification of Building Interior Decoration?Design GB 50222-95 appendix A, flammability,inflammability materials, flame retardency, noninflammability: combustion performance of A, B3, B2, B1 materials are divided into
- Q: What are the additives and recipes of refractory?
- SM water reducing agent
