Embodiment approach 1

[0012] High performance exothermic agent The exothermic agent is made from the following raw materials by weight: 5 parts of bauxite, 6 parts of boron nitride, 3.5 parts of magnesium chloride, 6 parts of zinc silicate, 7 parts of potassium chlorate, 2.7 parts of parts of sodium chloride, 7.4 parts of iron powder, 9.6 parts of diatomaceous earth, 5 parts of vermiculite, 4 parts of quartz sand, 3.7 parts of expanded graphite, 2.8 parts of calcium silica powder, 2.5 parts of potassium nitrate, 8 parts cryolite, 3.3 parts sodium bicarbonate, and 4.6 parts phlogopite. The particle size of each component raw material is preferably 50-300 mesh, and each component raw material is crushed and mixed uniformly to obtain a composite exothermic agent. Under the high temperature environment, the exothermic agent of this embodiment has a volume change rate within 13%, which makes the exothermic agent burn faster, generate more concentrated heat, and can rapidly increase the temperature, so t...

Embodiment approach 2

[0014] The exothermic agent of this embodiment is made from the following raw materials by weight: 4 parts of bauxite, 7 parts of boron nitride, 4 parts of magnesium chloride, 7 parts of zinc silicate, 8 parts of potassium chlorate, 2 parts of of sodium chloride, 7 parts of iron powder, 10 parts of diatomaceous earth, 6 parts of vermiculite, 3 parts of quartz sand, 4 parts of expanded graphite, 4 parts of silicon calcium powder, 3 parts of potassium nitrate, 9 parts of parts cryolite, 4 parts sodium bicarbonate, and 5 parts phlogopite. The particle size of each component raw material is preferably 100-350 mesh, and each component raw material is crushed and mixed uniformly to obtain a composite exothermic agent. In a high temperature environment, the exothermic agent of this embodiment has a volume change rate within 14%, a fast combustion rate, concentrated heat generation, can heat up, and has a large calorific value, which can be increased by more than 35% compared to the t...

Embodiment approach 3

[0016] The exothermic agent of this embodiment is made from the following raw materials by weight: 6 parts of bauxite, 5 parts of boron nitride, 3 parts of magnesium chloride, 5 parts of zinc silicate, 6 parts of potassium chlorate, 3 parts of of sodium chloride, 8 parts of iron powder, 9 parts of diatomaceous earth, 4 parts of vermiculite, 5 parts of quartz sand, 3 parts of expanded graphite, 2 parts of silicon calcium powder, 2 parts of potassium nitrate, 6 parts of parts cryolite, 3 parts sodium bicarbonate, and 4 parts phlogopite. The particle size of the raw materials of each component is 50-300 mesh. The raw materials of each component are crushed and mixed uniformly to obtain a composite exothermic agent. The exothermic agent can be powder or a block product pressed into a designated shape. In a high temperature environment, the exothermic agent of this embodiment has a volume change rate within 15%, a fast combustion rate, concentrated heat generation, can heat up, and...

Abstract

The invention relates to a high-performance heating agent. The high-performance heating agent is prepared from the following raw materials in parts by weight: 9 to 10 parts of diatomite, 4 to 6 parts of bauxite, 3 to 4 parts of magnesium chloride, 2 to 3 parts of potassium nitrate, 6 to 8 parts of potassium chlorate, 2 to 3 parts of sodium chloride, 5 to 7 parts of boron nitride, 7 to 8 parts of iron powder, 5 to 7 parts of zinc silicate, 4 to 6 parts of vermiculite, 3 to 5 parts of quartz sand, 6 to 9 parts of cryolite, 3 to 4 parts of expanded graphite, 2 to 4 parts of silicon and calcium powder, 3 to 4 parts of sodium bicarbonate, and 4 to 5 parts of phlogopite. The high-performance heating agent has the advantages that the volume change rate is controlled within 15% under the high temperature environment, the combustion speed is high, the heat is centrally generated, and the heating amount is increased by 35% or more in comparison with the traditional heating agent; the usage amount of the heating agent is smaller, the production cost is reduced, and the pollution emission is reduced.

Description

technical field [0001] The present invention relates to an exothermic agent, in particular to a high-performance exothermic agent. Background technique [0002] At present, most of the exothermic agents used in the melting and forming process of high-temperature alloy steel are configured according to the principle of aluminothermic reaction (such as exothermic agents made from metal aluminum, sodium nitrate, iron powder, wood chips, expanded graphite, etc.). During the use of the exothermic agent, due to the thermal expansion of the exothermic agent (at least 2 times), the burning speed is slow, the heating efficiency is low, and the heat is dissipated, resulting in low processing efficiency of high-temperature alloy steel, high temperature is difficult to achieve, and the required amount of use Larger exothermic products have high costs and are difficult to meet the needs of new technologies. SUMMARY OF THE INVENTION [0003] The present invention provides a high-perfor...
