Abstract
The present invention discloses a high wear-resistant preform for whole casting, wherein the high wear-resistant preform is prepared from the following raw materials by weight: 45-85% of compact corundum with a particle size of 8-0 mm, 1-10% of silicon micro-powder with a particle size of less than or equal to 0.1 [mu]m, 1-10% of silicon carbide, 5-15% of high aluminum cement, and 5-10% of a binding agent. According to the present invention, the high wear-resistant preform for whole casting is used to replace high aluminum bricks and steel bricks, such that the whole structure is stable, the wear resistance is provided, the cost is low, and the service life is 3-5 years.
Description
Technical field
The present invention relates to technical field of refractory materials, particularly relate to a kind of integrated poured high abrasion prefabricated component.
Background technology
The furnace throat of blast furnace, mainly protect furnace lining use, working temperature 400-500 DEG C, by shock and the friction of furnace charge, very easily weares and teares, and general steel brick and the high alumina brick of adopting is built by laying bricks or stones, and cost is high, and result of use is poor.
Summary of the invention
The technical problem to be solved in the present invention be the furnace throat of blast furnace by the shock of furnace charge and friction, very easily wear and tear, a kind of integrated poured high abrasion prefabricated component be provided.
Technical scheme of the present invention is: a kind of integrated poured high abrasion prefabricated component, is characterized in that, it is made up of the raw material of following parts by weight:
Granularity is the compact alumina 45-85% of 8-0mm
Granularity is the silicon powder 1-10% of less than 0.1 μm
Silicon carbide 1-10%
High-alumina cement 5-15%
Bonding agent 5-10%.
The invention has the beneficial effects as follows: the integrated poured high-strength wearable prefabricated component of the present invention, substitute high alumina brick and steel brick, one-piece construction is stablized, and wear-resistant, cost is low, and the life-span is 3-5.
