• 2 Units **0 mm x 2.**0 mm B.L.
• 1 Unit **0 mm
• 2 Units **0 mm

Plus a complete set of chills, chillers and moulding tackle to cast all kind of rolls including big section rolls with the barrel shaped with grooves and collars in as-cast condition.    


-HEAT TREATMENT

During the manufacturing process of rolls, many materials need to pass one or more heat treatment to further achieve the most appropriate mechanical properties and good microstructure. The resistance furnace of TS ROLL can achieve multi-point precise temperature control to ensure uniformity of the furnace temperature. Between different furnaces, we use a unified computer control to achieve the furnace heating and cooling consistency in order to ensure the rolls from different furnaces with same microstructure and performance.
