Description

Шихта готовитс  путем совместного помола графита, карборунда, каменноугольного пека и ферросилици  до полного прохода через сито 4900 отв/см2 ( .0,088 мм). Прессование изделий осуществл етс  на гидравлическом прессе при удельном давлении прессова«и  400-600 кг/см непосредственно из тонкозернистых масс.The mixture is prepared by joint grinding of graphite, carborundum, coal tar pitch and ferrosilicon until it passes through a sieve of 4900 holes / cm2 (.0.088 mm). The pressing of the products is carried out on a hydraulic press with a specific pressure of the press and 400-600 kg / cm directly from the fine-grained mass.

Физико-механические свойства изделий приведены в таблице 2.Physical and mechanical properties of products are given in table 2.
