Problems solved by technology
Traditionally, water-cooled furnace rolls of heat-resistant alloys with Cr25Ni20Si2, Cr25Ni35Nb1.5 or Cr28Ni48W5 jackets are used, but heat-resistant alloy furnace rolls have high cost (generally accounting for about 25% of the total cost of the furnace), and the roll surface is prone to nodules (will Inherent shortcomings such as pitting defects on the surface of the steel plate) and large heat loss

The invention discloses a water-cooled furnace roller with a refractory fiber layer. The furnace roller also includes a refractory fiber layer sleeved on the outside of the roller and a water-cooled core tube located in the roller. The shaft head on one side of the roller is provided with a through hole. The shaft head on the other side of the roller is provided with a receiving groove, and the water-cooling core tube passes through the shaft head with a through hole and is inserted into the receiving groove. There is a gap between the through hole and the receiving groove and the water-cooling core tube; Both ends of the refractory fiber layer are respectively provided with fixed baffles and movable baffles. A guide tube is set outside the water-cooled core tube. The guide tube and the water-cooled core tube are fixedly connected together through round steel. The guide tube is connected to the roller. are fixedly connected together by round steel; the refractory fiber layer includes multiple circular asbestos fiber ring pieces and stainless steel ring pieces spaced along the length of the roller. The furnace roller of the present invention has good high temperature resistance, does not adhere to the oxide scale, and has certain load-bearing operation performance after being pressed. It is an important technological innovation that solves the defects of steel plate roller printing.
Description
technical field [0001] The invention relates to a roll, in particular to a water-cooled furnace roll with a refractory fiber layer and a preparation method thereof. Background technique [0002] Roller hearth heat treatment furnace is the main equipment for solid solution and annealing heat treatment of special steel such as medium and heavy plate stainless steel, and is the key large-scale equipment of medium and heavy plate heat treatment line. Compared with other furnace types, it has the characteristics of high-speed furnace, which shortens the quenching transfer time of the steel plate, and can be equipped with advanced roller quenching equipment after the furnace. It has been widely used in medium and thick steel plate factories at home and abroad. [0003] Furnace roll is a very critical part of high temperature roller hearth heat treatment furnace. The maximum solid solution temperature of high temperature solid solution roller hearth furnace can reach 1200 ℃. The fu...
