Abstract
The invention discloses a device for producing decorative materials through liquid blast furnace slag. The device is mainly composed of a slag conveying tank (1), an intermediate slag tank (2), an alternating-current electric arc furnace (3), a cooling box (4) and a calender (5 ). By the adoption of the device for producing the decorative materials through the liquid blast furnace slag, waste heat of the melted blast furnace slag is effectively utilized, the melted blast furnace slag is subjected to resource recycling, and the utilization rate of resources is increased; by the adoption of the difference of the chemical composition, the chemical property and the color of the melted blast furnace slag and auxiliary quenching and tempering raw materials, the melted blast furnace slag and the auxiliary quenching and tempering raw materials form a inter-occlusion inter-infiltration structure manner, the colorful decorative performance with the natural texture is formed, the abundant mineral substance of the melted blast furnace slag is subjected to high-temperature smelting, and the overall mechanical performance is excellent; and the high-temperature liquid slag is provided by the adoption of a furnace bottom slag overflow manner, it is guaranteed that slag raw materials with the stable flow, temperature, components and viscosity are continuously provided for a production line, a foundation is laid for the guarantee of producing high-standard high quality building decorative material products on the production line, meanwhile flushing of electric arc furnace refractory is reduced in the material adding process, and the continuous service life of the refractory is guaranteed.
Description
technical field [0001] The invention belongs to the field of resource utilization of waste, and relates to a comprehensive utilization technology of utilizing liquid blast furnace slag, in particular to a device for producing decorative materials from liquid blast furnace slag. Background technique [0002] With the development of modern construction industry, high-strength, beautiful and multi-variety requirements are put forward for decorative materials. It is in this situation that artificial facing stones appear. It has high strength, corrosion resistance, pollution resistance, convenient construction, and artificially controllable patterns. It is an ideal decorative material for modern buildings. However, the price is relatively high, the corrosion resistance is poor, and micro-cracks are prone to appear, so it is only suitable for plates. Due to the adhesive materials used in the production, even some inferior products will have excessive benzene, formaldehyde, lead,...
