 Before filling, the electrode paste shall be broken into 80 ~ 100mm small pieces, so that the electrode paste can pass between the two ribs smoothly. If the particle size is too large, the electrode paste suspension fault is easy to occur; If the particle size is too small, it is easy to cause paste spraying. It is better to buy the finished electrode paste. If the material supplied by the manufacturer is qualified, it can be directly filled. The powder of broken electrode paste is reduced, the utilization rate of electrode paste is improved, and the cost of calcium carbide is reduced. Use a forklift to transport the electrode paste to the carbide furnace with a trolley or special tools, and use an electric hoist to lift the electrode paste into the electrode barrel. Pay attention to lifting * during filling. 　　When installing the electrode paste, pay attention not to scatter the electrode paste on the equipment outside the electrode barrel, so as to avoid the electric ignition a

 Use process and consumption of electrode paste in terms of use characteristics, electrode paste is a continuous self baking electrode. During use, its outer layer is a cylinder made of 1-2mm thick steel plate. The electrode paste is regularly added into the cylinder. With the progress of production, the electrode paste is gradually softened, melted and roasted. During roasting, a large amount of volatiles are released. After entering the conductive clip of the electrode, due to the high-temperature effect, it is from semi coking to complete coking, * and becomes a conductive carbon electrode. The electrode paste is baked into a conductive electrode by various heat of the electric furnace itself, so it is called a self baking electrode. During the working process of the electrode, a section of cylinder is connected to the top of the electrode at regular intervals, and a certain amount of electrode paste is added, and the process is repeated.

 　　The so-called oven drying is an operation that uses heating method to gradually adapt the furnace lining and electrode to charging smelting. Its main purpose is to dry the furnace lining and roast the electrode paste. The quality of oven drying will not only affect the service life of the furnace lining, but also directly affect whether the electric furnace can be put into operation smoothly. Therefore, the oven drying system table should be formulated in detail and strictly implemented in the opening plan. 　　Coke oven 　　There are three methods in the stage of oven drying: wood drying, oil drying and coke drying. This paper only introduces the coke drying. As the name implies, coke baking is a method of baking the furnace by using the combustion heat of coke. Large metallurgical coke with less ash shall be used to make fuel (particle size > 150mm). During the baking of electrode paste, it shall be ensured that the coke burns close to the electrode and is added in time. I

 The mechanical strength of electrode paste includes compressive strength, flexural strength and tensile strength 　　The electrode paste height refers to the height from the upper end of the electrode clamp to the top of the electrode paste. If the electrode paste is too high, the coarse and fine particles in the electrode paste are prone to delamination, or the electrode barrel is damaged due to the pressure of the paste column is too high. If the electrode paste column is too low, it is difficult to obtain a dense electrode due to the pressure of the paste column is too small and the filling property is poor. The electrode paste is consumed too quickly. The proper height of electrode paste column can improve the quality of electrode baking and reduce consumption. 　　Electrode paste is the conductive electrode of various submerged arc furnaces and is an indispensable product in industrial production. In the national standard of electrode paste, there is no mechanical strength q

 When the sintering temperature of the electrode paste is between 300 and 800 degrees, because the volatile matter of the coal tar pitch has been discharged, the remaining coal tar pitch has been carbonized to form a network, and it is fused with various electrode paste raw materials, and the mechanical strength reaches the standard value. Our Rongxin Carbon technicians have calculated that the compressive strength of the electrode paste at this time is 17-33 MPa, the flexural strength is 7--17 MPa, and the tensile strength is 4--8 MPa. After the electrode below the copper tile of the submerged electric furnace enters the smelting process, the temperature of the electrode will rise further due to the further increase in the temperature of the raw material, and the mechanical strength will increase with the rise in temperature. The temperature of other materials rises to 1500 degrees. When the mechanical strength drops sharply, such as heat-resistant alloys, the mechanical strength of c

 The so-called oven is an operation in which the furnace lining and electrodes are gradually adapted to the feeding smelting by heating, and its main purpose is to dry the furnace lining and baking the electrodes. The quality of the oven will not only affect the service life of the furnace lining, but also directly affect whether the electric furnace can be put into production smoothly. Therefore, the furnace system should be formulated in detail in the furnace opening plan and strictly implemented. Coke oven In the first stage of the oven process, there are three methods of wood baking, oil baking and coke baking. This article focuses on the focus on the focus baking. As the name implies, coke baking is a method of oven using the combustion heat of coke. Large metallurgical coke with less ash content should be used to make fuel (particle size> 150 mm). During the baking of the electrode, the coke should be burned close to the electrode. Add it in time. In order to help the coke bur
