EXAMPLE OF DECARBURISING PHENOMENA DURING THE CARBURASING HEAT TREATMENT PROCESS
Carburizing is a very popular method of thermochemical treatment to increase the surface hardness of steel parts. It is achived by heating the steel at an austenite temperature in an environment of appropriate carbon source. Carbon sources provide the corresponding so-called a carbon potential (C potential). In the case of equilibrium state, the ca...

THE UTILIZATION WASTE HEAT OF FLUE GAS IN A HOT DIP GALVANIZING PROCESS
In this paper will be presented a practical example of the fuel savings in the process of hot-dip galvanizing. Reconstruction of the line is carried out during the transition of equipment from one to another location. Total power of the melting furnace it was 2.4 MW, and hot air generator for drying oven, has a power of 600 kW. With ...

HEAT TREATMENT OF LOW CARBON STEEL SCREWS IN THE STRAIGHT FLOW FURNACE
Steels for screws, nuts and rivets are usually low carbon steels, carbon steels or quenched and tempered low alloy steels. From these are required precisely defined strength properties, hardness and toughness, which determine the so called class strength of screws. This paper describes the thermal treatment of hexagonal screws with s...
