Tanlin carbon electrode paste product moulding characteristics

Tanlin carbon electrode paste products as a kind of carbon products, its moulding has the common point of carbon products, but also has its special place, the reason why the moulding of electrode paste products is special is mainly decided by the performance of the products, the electrode paste is the raw material of self-baking electrode, and its baking process is completed in the calcium carbide and ferroalloy mineral heat furnace, That is to say, the baking speed and time of the electrode paste is variable, which is decided according to the furnace type of the mineral heat furnace. That is to say, the baking speed and time of the electrode paste is variable, depending on the furnace type, melting varieties, geometrical and electrical parameters of the mine-heated electric furnace. Roasting speed and time of the variability of volatile content and plasticity of electrode paste products have a variety of models, most of the electrode paste products volatile content is much higher than the general carbon products, which determines the electrode paste is difficult to use or not necessary to use vibration moulding and isostatic pressure forming, the main use of compression moulding and extrusion moulding. Extrusion moulding and general carbon products performance is basically the same, but due to the continuity and large amount of electrode paste products production, China’s electrode paste manufacturers basically use the class of mould compression moulding. The so-called class compression moulding refers to the characteristics of compression moulding, but not the traditional sense of compression moulding, the pressure is not transmitted by the external indenter, mainly relying on its own gravity to pressurize the lower electrode paste products, and the model at the bottom of the continuous movement, forming a moulded block.

The biggest advantage of this feature also lies in the shape of the moulded product can be moulded according to the different products required by the mineral heating furnace to make the most suitable scheme, for example, trapezoidal block, round ball paste, flying disc paste, columnar paste.
