Example Embodiment

[0037] Example one

[0038] A steel mill ladle drainage sand, the product formula contains 60 to 70 parts of chromium ore, 5 to 15 parts of alumina balls, 20 to 30 parts of desert sand and 1 to 5 parts of performance modifier. The performance modifier is Flake graphite, super carbon black and semi-reinforced carbon black are mixed in any proportion; among them, Cr in chrome ore 2 O 3 The content of ≥45%, the particle size is 0.2~0.9mm, and 80 mesh ≤ 3%, 20 mesh ≤ 2%, moisture ≤ 0.5%, calculated by weight percentage; SiO in desert sand 2 The content is ≥94%, and the particle size is 0.5~1.2mm.

[0039] Using the production process of the drainage agent of the present invention to produce the above drainage agent can be carried out as follows:

[0040] A. According to the particle size requirements of the raw materials in the product formula, sieving the chromium ore and desert sand to the corresponding particle size respectively, and measuring the composition of each raw material afte...

Example Embodiment

[0041] Example two

[0042] A steel factory ladle drainage sand, the product formula is 60-76% of chromium sand, of which the Cr in the chromium sand 2 O 3 The mass percentage content of ≥45%; sea sand 10-20%, alumina ball 4-9%, desert sand 4-9%, potash feldspar 3-5%, carbon black 0.3-0.8%, flake graphite 0.3- 1.0%. The production process of the drainage agent of the present invention is used to produce the above-mentioned ladle drainage agent. The production steps are the same as those in the first embodiment. The difference is: step B, in the drying process, the drum kang speed is controlled at 450 rpm, and the air is induced The temperature is controlled at 200°C; in step G, carbon black and flake graphite are fed from a separate silo into a closed mixing tank, and the mixing time is controlled at 20 minutes to obtain a finished product.

Example Embodiment

[0043] Example three

[0044] The ladle drainage agent of a steel plant is made of the following raw materials: The mass distribution ratio is as follows: chromium sand 50-80%, white quartz sand 10-30%, fused magnesia 8-20%, and the particle size of each raw material is controlled within the required range Inside.

[0045] The production process of the ladle drainage agent of the present invention is used to produce the above-mentioned ladle drainage agent. The production steps are the same as those in the first embodiment. The difference is: step B, in the drying process, the drum kang speed is controlled at 300 rpm, The wind temperature is controlled at 150°C; in step G, the fused magnesia is fed from a separate silo into a closed mixing tank, and the mixing time is controlled at 30 minutes to obtain a finished product.

Abstract

The invention provides a production technology for a drainage agent and belongs to the technical field of metal smelting. Gas provided by a gas generator is combusted in a hot blast stove to serve as a heat source, and various raw materials are dried in a heatable roller brick bed firstly; then the raw materials are cooled through air cooling and conveyed into corresponding bins, automatic discharging and carbon adding are conducted according to the ratio of a formula, and even stirring is conducted in a closed stirring tank; and then automatic packaging is conducted, and warehousing is conducted. A full-automatic production line is adopted for the integral technology, stability of the product quality is ensured, in addition, the number of working personnel is reduced, and the labor cost is reduced; and meanwhile, the influences of human factors on the product quality are also greatly reduced, dust removing devices are arranged for links where dust is liable to be generated on the heatable roller brick bed and the sealed stirring tank so that generated dust can be collected and removed, dust pollution is reduced, the environment-friendly standard is improved, and clean and efficient production is achieved.

Description

technical field [0001] The invention belongs to the technical field of metal smelting, and in particular relates to a production process of a drainage agent. Background technique [0002] The ladle drainage agent is a kind of unshaped refractory material, which is added into the upper nozzle of the ladle and can be automatically poured during the continuous casting ladle pouring process, so that the production process is continuous and the casting is guaranteed throughout the process. It is a necessary refractory material. [0003] Due to the overcapacity of steel in recent years, most iron and steel enterprises are in a state of meager profit or even a loss. Iron and steel enterprises have greatly reduced the purchase price of raw materials and fuels to increase profit margins. The price of raw materials such as chrome ore imported from South Africa is rising steadily. In order to increase profit margins, it is necessary to reduce costs in intermediate production links. The...
