Luoyang City Kelder Refractory Materials Co. Ltd's constant pursuit, constant innovation does not stop.Beginning in 2018, with the country's seismic design standards for buildings increased. The market demand for a large number of HRB400, 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, some steel mills intermediate packages used 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, resulting in a great waste of 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 package set to play the dry material, has achieved remarkable results: the first time to play a new package after repeated use of 2-3 times, down the line after the bottom of the package trimming, do not dismantle the package wall re-introduced into the tire set to play, can be reused 2-3 times to continue to set to play, repeated use, and save a lot of middle packages. Save a lot of intermediate packet dry material, turn a loss into a profit.
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 their own use, limited capacity, limited to 10 refractory partners
