Luoyang City Kelder Refractory Materials Co. Ltd's constant pursuit, constant innovation does not stop.Starting in 2018, with the government's increase in seismic design standards for buildings. The market demanded a large number of HRB400 and HRB400e steel grades. Thus steel smelting generally improve the manganese content, the original refractory design standards need to be further improved and optimized in order to meet the manganese content increase on the refractory stronger resistance to scouring, erosion resistance, and with the production of the accelerated compact, the pulling speed is generally increased, but also put forward a more demanding requirements for refractory materials.

Luoyang City Kelder Refractories Co., Ltd. according to the actual situation of steel mills, the establishment of a specialized group, and scientific and technological institutions, after repeated experiments in the laboratory and the use of steel mills, in August 2018, research and mature put on the market of the new type of neutral dry material, in Shanxi, 3 steel mills, Xinjiang, 2 steel mills, as well as Hebei Langfang, a steel plant, Xuzhou, and other steel mills used to obtain a good use of the results.

Solve the problem of high pulling speed, high manganese content on the intermediate pack lining erosion serious problems, so that high manganese steel intermediate pack life significantly improved, the labor intensity of workers to reduce the production efficiency greatly improved.

The new neutral dry material has the following advantages:

1、With the advantage of cost-effective

2、Simple baking, easy construction.

3、Excellent heat preservation performance, the second baking has good strength in high temperature.

In 2021, with the decline in the efficiency of iron and steel enterprises, some especially electric furnace steelmaking compression production time, staggered production, the use of some steel mills intermediate packages from the original 24-48 hours compressed to 8-20 hours, the steel production is reduced, but the intermediate packages of materials but did not reduce the material, resulting in a great deal of waste, a lot of contractors contracted by the ton of steel loss of a serious loss of our company contracted intermediate packages also into the loss.

In this context, our company according to the market dynamics quickly start the technical reserve program; in my company contracted intermediate package project first use can be repeated many times to use, do not turn over the packet set to play the dry material, has achieved remarkable results: playing a new packet repeatedly used 2-3 times, down the line after the bottom of the packet trimming, do not dismantle the packet wall re-introduced into the tire set to play, can be reused for 2-3 times to continue to set to play, repeated use, saving the A large number of intermediate packets of dry material, turning losses into profits.

Luoyang City Kelder Refractories Co., Ltd. lapping materials, lapping construction now has a complete set of solutions. Now call for 10 partners to share the results of this technology; the use of my company sets to play dry material, my company can provide a complete set of technical solutions.

Since our company first meets the needs of its own use, limited capacity, limit 10 refractory partners

Enterprise Honor

In 2017, it was recognized by Luoyang Science and Technology Bureau as the first batch of municipal enterprise R&D center in Luoyang.

In 2017, the company's independent research and development of dry material to obtain China's invention patent (CN105777158A) to fill the gap in the market has achieved significant economic and social benefits.

In 2018, it was recognized as a high-tech enterprise in Luoyang City.

Obtained Science and Technology Enterprises in Henan Province in 2018

Received several patents for utility inventions from 2022 to date

Luoyang City Kelder Refractories Co., Ltd. is committed to the research and development of steelmaking intermediate ladle, safety and improvement.

The independently developed neutral dry material was awarded a patent for invention.

The dry material developed for high drawing speed and high manganese steel water is characterized by erosion resistance, scouring resistance, smoothness and high strength, which has made outstanding contribution to energy saving and cost reduction for steel mills and cooperative customers, and achieved remarkable economic benefits.

The experiment was successful! The 48+ hour experiment package came off the line successfully!

April 21, 2021 Luoyang City Kelder neutral dry material Hebei a steel plant in the package contracting plant in the package of experimental packages successfully down the line: the use of time: more than 48 hours, the erosion of fine, uniform and smooth.

High drawing speed, high manganese steel type special dry material

At present, most of the intermediate ladle working liner dry material used in steelmaking is magnesium dry material. But magnesium dry material mainly used raw materials for magnesium sand, magnesium sand using sintered magnesite or electrofusion magnesite method of production, sintering and smelting costs are very high, and magnesium sand bulk density is high (generally 3.2g/cm3), the production of dry material bulk density is generally 2.4g/cm3 or so. Because of the high thermal conductivity of magnesium dry material, in the steelmaking process requires a higher molten steel temperature, baking intermediate package of about 800 ° C to make up for the loss of heat, greatly increasing the cost and waste of resources.

Luoyang City Kelder Refractories Co., Ltd. uses the main material with silica sand, additional other materials produced by the neutral dry material of the bulk density is generally about 2.0g/cm3, with good thermal insulation properties, and good use of the effect of energy saving and environmental protection. Obtained the national invention patent: (Patent No. CN105777158A), and achieved significant social and economic benefits.
