in the implementation of the knives to sieczkarni robbing edges prolonged steel part (1) by their nest (1a) for reinforcement. within these nests ((1a) edges prolonged steel part (1) strengthens.the prolonged steel part (1), a steel to improve the heat and as strengthening imposed plate (2) of cemented carbide, and subsequently at austenityzacji steel, which is made of elongated steel (1), the plate (2) with w u0119glik u00f3 in the sintered material is combined with the prolonged steel part (1) by means of soldering brazing.using soldering extending composite beneficial based on brass, while during soldering is the lutownicz u0105 ranges from 0.2 mm to 0.8 mm, and the whole is subjected to cooling rate to obtain the transformation martenzytycznej or bainitycznej in the longer period of steel part (1).the prolonged steel part (1), a steel with a carbon content of beneficial beneficial 0,22% to 0.33%. a plate (2) is used spiek tungsten carbide with cobalt wc - what species of mining of cobalt content by weight from 10% to 30% of wc grains and carbides below 35 mm.
