Product Description:


Molten iron insulation agent

Product description

The molten iron insulation agent is my company to cater to the needs of the market development of metallurgical products. The product effectively substitute the traditional use carbonization rice and other carbonaceous materials, solve the high, transportation agent water covered the defects in use and to appear in the heat loss, and easy to crusting, stick the furnace wall, hang slag etc, it is home to more than in normal use steel mill, and get good use effect and high reputation from the customers.

Product features

1. Spread good performance and can even coverage of the iron liquid surface;

2. Strong heat insulation, heat preservation time long, iron temperature drop small;

3. Product ingredients stability, rare slag performance is good, use not crusting, not erosion bag wall, and turn packets clean, reduce the workload of qing bag;

4. Product alkalinity ?

Into a

SiO2        CaO        fixed C bulk     melting     point
             

Refers to the standard

10~18     10~18        30~45         <1150℃     <0.8

Usage and dosage

Molten iron by the bag, directly add to the molten iron liquid surface department, addition amount depends on the molten iron residence time 1 ~ 1.5 kg per ton steel according to choose.

Q:Which are fireproofing external wall materials?
For example, Grade-A waterproofing external wall thermal insulation material: glass wool, foam glass, foam cement, hole-closed perlite, rock wool; Grade-B1 waterproofing external wall thermal insulation material: XPS after special treatment. There are also PU after special treatment, phenolic aldehyde and gelatine powder polyphenyl granule. Grade-B2 waterproofing external wall thermal insulation material: PE, and EPS. Grade-A: Completely fireproofing buliding material. Without probility of burning, completely fireproofing buliding material is expensive and unnecessary for home decoration. It is usually used in arsenal and electrical equipment department store. Grade-B1: nonflammable building material: With good flame resistance, nonflammable building material will not burn in the air or at high temperature, but it maby burn in the air and at high temperature. But when the fire source ransfers, it will be out immediately. Grade-B2: combustible building materials. Due to its small firresistance, it is easy to burn in the air or at high temperature, such as wooden building materials. The above are external wall fireproofing material of different classes.
Q:What are the characteristics of phenolic resin as a refractory material?
Q:What is the type of heat resistance property of high temperature electric furnace ?
According to the levels of refractoriness : Common refractories: & Gt: 1580 ℃ ~ 1770 ℃ advanced refractories: 1770 ℃ ~ 2000 ℃ AAA refractories; 2000 ℃
Q:What is carbon composite refractories? I hope that the answer is in detail.
Q:What are the requirements of the performances of brasque refractory?
Physical properties of refractories include structural property, thermal property, mechanical property, usability and operation property. Structural properties of refractories include porosity, bulk density, water absorption, air permeability, pore size distribution,etc.. Refractory thermal properties include thermal conductivity, thermal expansion coefficient, specific heat, heat capacity, thermal diffusivity, thermal emissivity. Mechanical properties of refractories include compression strength, tensile strength, breaking strength, torsional strength, shear strength, impact strength, abrasion resistance, creep property, bonding strength, elasticity modulus. usabilities of refractories include refractoriness, refractoriness under load, reheating linear change, thermal shock resistance, slag resistance, acid resistance, alkali resistance, water resistance, corrosion resistance to CO, conductivity, oxidation resistance, etc.. Operation properties of refractory include consistence, slump, fluidity, plasticity, cohesiveness, resilience, coagulability and hardenability,etc. I hope you can solve the problem with my answer.
Q:Is fireclay corrosive?
No. All of the refractory materials have stable chemical properties and their usability can be guaranteed under high temperatures.
Q:Which industry does refractory belong to? Does it belong to construction industry?
I am engaged in construction. Refractory material does not necessarily belong to construction industry. Fire resistance is only a part of material performance. Indeed, there are many places requiring refractory accorded with fire resistant level.
Q:What's the refractoriness and how to measure the refractoriness?
Bottom each side length is 8 mm and upper side length is 2 mm. Under a certain temperature-rising speed, when heating, refractory's resistance to high temperature from melting is called refractoriness. The properties of cross section into an equilateral triangle and height is 30 mm. When it bends down until the vertex and chassis contact temperature is the refractoriness of sample. It bends due to the influence of its weight. Make the will-measured material into standard pyrometric cone.
Q:What are the raw materials of refractory? And what are their names?
Q:Does anyone know the refractory temperature of fire-resistant glass?
Ordinary glass will be completely liquefied in the furnace of about 1100 degrees for half an hour and will not deform below 600 degrees. toughened glass fire-resistant glass is the product of ordinary glass after being processed Glass will mainly burst after encountering fire. When unevenly heated or encountering sudden drastic changes in temperature, ordinary glass will burst if the sharp temperature difference is over 70-120 degrees and toughened glass will burst at 200 degrees. It is not yet clear of the bursting temperature for the refractory glass. If the overall glass is not heated evenly, it will have no significant change below 600 degrees, and it will deform with the increase of temperature until melting. The fire-resistant time of the glass you said is the time to heat the glass into the extreme temperature differences it can endure, which should not be more than 10 minutes
