After lining of blast furnace has been masonry.Before putting into operation, there are many matters of attention. And as a refractory service provider, This is very necessary for the user to make a hint.Today we will summarize the precautions for the use of the new blast furnace and how to increase the service life of the blast furnace.
1. The newly produced blast furnace should avoid too fast production and the basic work should be done well. To make iron first, the time is about 10-20 days. This will enable the hearth to form a layer of graphite carbon at the very beginning to seal up some brick joints. It is beneficial to the formation of furnace bottom and hearth protection layer, which is beneficial to the service life of blast furnace.
2. While ensuring enough cooling water, We should pay close attention to the leakage of cooling equipment. In particular, the tuyere and the cooling wall. If there is a leakage of water, it is necessary to deal with it in time.
3. Pay attention to pre-furnace operation.Maintenance of blast furnace tapping port and iron mouth depth adapted to the furnace capacity of the blast furnace.Pay attention to the speed and times of iron production,Control the mud pack in the furnace,The general mud bag is good at 600mm-800mm.
4. Finish the furnace fine material well. The harmful elements in the furnace are within the prescribed limits. It is strictly forbidden to exceed the standard to enter the furnace.Ensure that the coke reaching the hearth has good air permeability. Reducing the erosion and erosion of the molten iron circulation on the side walls of the hearth, and removing the harmful substances regularly.
5. After one year of production, the first protection of the furnace was carried out. To ensure that the thickness of the protective layer and brick lining of the side walls of the blast furnace hearth is within the controlled range. Then, according to the hearth condition or half a year, the furnace protection work is carried out.
6. Select responsible refractory suppliers and high quality refractories. To do good basic work for the blast furnace, Responsible and powerful refractories enterprises provide standard indicators refractory materials for blast furnace lining.High standard and high demand masonry work should be done during masonry.
The above five points need to be paid attention to after the blast furnace is put into operation. The premise of increasing the service life of blast furnace is the excellent quality of refractories. Therefore, it is not easy to choose a good supplier of refractory materials. Lite is a professional refractories manufacturer and service provider.More than 50 years since the establishment of the factory, No matter from product, technology, sale, etc., they are far ahead in the refractory industry. Lite has been continuously developing and innovating, cooperating with China's Refractories Research Institute and university research laboratories. The introduction of refractory professionals, equipped with advanced equipment, research and development of new products, improve product performance, only for users to ensure the quality of refractories and use effect. The aim of Lite is to increase the service life of the lining in the kiln. It means that we can save 10% of the earth's resources and reduce 10% of the pollution.
