Product Description
Silica Brick For Hot blast stove
Silica refractory brick for hot blast stove is used to build siliceous refractory products with tridymite as the main crystal phase in the high-temperature part of blast furnace hot blast stove.
Hot blast stove silica brick has the following characteristics:
(1) Under long-term high temperature and load conditions, the volume is stable and the high temperature creep rate is low, and one
or even two blast furnace campaigns can be used continuously.
(2) Good thermal shock resistance above 600℃. Adapt to the variability of the temperature of the hot blast stove to keep bricks
and masonry intact
(3) The chemical resistance is better than clay bricks and general high alumina bricks. The corrosion of the alkaline substances
in the gas and smoke on the silica bricks is limited to the formation of a layer of glass on the surface, and no peeling occurs.
(4) The thermal conductivity of silica bricks is larger than that of clay bricks and high alumina bricks, which is conducive to
storing and releasing heat in a shorter time.
The shape of the product should be regular and the size deviation should be small. The hole diameter of the checker bricks should
be ±1mm. The bricks used in other parts should not exceed ±1%. If the joints of the upper pipes of the external combustion hot
blast stove are made of composite bricks, they must be cut before masonry. Grind and pre-assemble. The width of the surface crack
is not more than 0.5mm, and there should be a length limit side. Cracks with a width of less than 0.1mm will not affect the use,
and there should be no cracks caused by improper cooling.

Company Profile
Luoyang Fangshan refractory material Co., Ltd. is located at the foot of Fangshan, tiemen Town, 40km west of Luoyang, and close to 310 National Highway and Lianhuo Expressway in the north. It is adjacent to Longhai railway special line in the south, and the transportation is very convenient. Moreover, the silica in tiemen Fangshan has high grade and large reserves. It is an important raw material base for high-quality silica bricks in China.
Founded in 1986, the company was formerly a subordinate enterprise of Lobo group. Integrating the technical advantages of Lobo group and Sinosteel luonai Institute, the company developed high-quality silica brick. In 1998, our company participated in the formulation of the national standard of high-quality silica brick in China. It was restructured into a private enterprise in 2001. Under the leadership of Mr. Wang Guihong, chairman of the board of directors, the enterprise scale, product quality and economic
The business philosophy has made great progress, and now it has developed into having more than 85 million fixed assets and annual sales revenue
With more than 55 million employees, 120 employees, 10 undergraduate graduates and 10 middle and senior engineers, it is a large-scale manufacturer specializing in the production of silica bricks for tank calciner.
As the "formulation and revision unit of national standard for high quality silica brick in 1998", the company has been committed to product R & D and process innovation. Since 2010, our company has regarded high-quality silica brick as the company's "fist product", continuously developed and innovated, strengthened product R & D and strengthened the construction of product quality system. According to the damage mechanism of different furnace type silica bricks, our company has innovated its production process and production equipment, and successfully developed low air hole and high density silica bricks, and its physical and chemical indexes far exceed the national standards. The product has the remarkable effects of anti-corrosion, high thermal conductivity, low energy consumption and long service life in practical use. According to the actual evaluation of users, the furnace life has increased significantly, which is highly praised by the majority of consumers.
The company has a high-quality silica mining and processing production line, which provides a reliable guarantee for the source of raw materials for the company. It has four large wet mills, two 800 ton CNC presses, two 630 ton CNC presses, four 500 ton presses, four 400 ton CNC presses, one 180 meter automatic gas tunnel kiln, with an annual output of 25000 tons of high-quality silica bricks and light insulating bricks
And 10000 tons of bulk materials. The company has complete quality inspection and testing center and product research and development center, and carries out monitoring and testing of the whole process of product quality, ensuring the advanced quality and reliability of the process. Every month, the company carries out vocational skills training and safety production training for all employees to continuously improve the process quality of products on the premise of safety production. The company implements the last elimination system to eliminate incompetent employees and managers in time to ensure the healthy development of the company.
