Abstract

The invention provides a special graphite carbon sleeved roller for a corrosion-resistant and abrasion-resistant continuous annealing line and a manufacturing process thereof, and relates to the technical field of non-oxidation continuous annealing production of strip steel, and the special graphite carbon sleeved roller is designed for solving the technical problems that an existing furnace roller is poor in corrosion resistance and abrasion resistance and high in cost. The special graphite carbon sleeved roller for the corrosion-resistant and abrasion-resistant continuous annealing line comprises the following components in percentage by mass: 80-90% of C, 1-3% of Al, 1.2-3.0% of Si, 0.4-1.3% of Ti, 2.5-3.5% of Mg, 1.8-3% of Ca, 0.9-1.8% of Fe, 1.2-2.1% of Na and 1-2.3% of W; and the manufacturing process of the special graphite carbon sleeved roller comprises the following steps: additive preparing, impregnation and roasting. The embodiments of the invention are used for improving the corrosion resistance and abrasion resistance of furnace rollers.

Description

technical field [0001] The invention relates to the technical field of non-oxidative continuous annealing production of strip steel, in particular to a special graphite carbon sleeve roller for an anti-corrosion and wear-resistant continuous annealing line and a manufacturing process thereof. Background technique [0002] With the increasing demand for a large number of high-quality cold-rolled thin steel sheets of various specifications, a continuous annealing production line (CAL / CAPL) suitable for continuous and mass production has been developed. The continuous annealing furnace unit is generally composed of a heating furnace, a soaking furnace, a cooling furnace and an aging furnace. Nitrogen and hydrogen protective gases are used to realize oxidation-free annealing of the steel strip. [0003] Furnace rolls are generally divided into heat-resistant alloy steel rolls (cast as a whole), graphite sleeve rolls (carbon sleeve rolls), all-ceramic furnace rolls, ceramic core...
