Abstract
The utility model relates to a high chromium combined cast iron roller. According to different technical requirements of the working parts of the roller, the high chromium combined cast iron roller is divided in to a roller sleeve made from high chromium cast iron and a roll centre made form ductile iron, alloy cast iron or cast steel. Different forming methods and different heat treatment processes are adopted to obtain different mechanical properties, then adhesives or the formula of motionless combination is adopted to wholly integrated the roller sleeve and the roll centre.
Description
The utility model relates to a kind of metal roll, especially a kind of combined high-chromium iron-cast roller.
The roll of using in the steel rolling industry, mostly once-forming through the roughing after-baking, carries out fine finishining again to cast spun casting or composite casting.This roll is a monolithic devices.Because roll surface requires high rigidity roll centre and roller neck then to require obdurability, so heat treatment often can only the two take into account.Along with the development of high-abrasive material, the two heat treatment mode of taking into account can not satisfy the production needs of high-quality roll.
The purpose of this utility model is in order to overcome the above-mentioned shortcoming of traditional handicraft, to bring into play sclerosis and the Strengthening and Toughening effect of Technology for Heating Processing to metal material to greatest extent, to satisfy the requirement of the different mechanical performances at each position of breaker roll aborning.
Basic structural feature of the present utility model as shown in drawings, it is the different technologies requirement by the roll working position, is divided into good roll centre (2) two parts of high roller shell of material hardness (1) and material toughness and tenacity; These two parts are selected for use respectively, different manufacturing process and different Technologies for Heating Processing, thereby make them obtain different mechanical performances; At last, can select bonding agent or adopt the mode of static cooperation that roll surface and roll centre are carried out entire combination for use.
A specific embodiments that meets the utility model essential characteristic is finished like this
1, selects the suitable high-chromium white cast iron of chemical analysis by cast form or in addition die forging again, make it stand the heat treated process of high temperature repeated deformation.Produce like this as the roller shell in the accompanying drawing (1); Outside dimension after the roller shell fine finishining is a roll working position diameter dimension, and internal diameter is the fit dimension of roll centre, and length is the face length size of roll.
2, select again chemical analysis suitable such as spheroidal graphite cast-iron or alloy cast iron or cast steel, the method by common casting is produced roll centre (2), the roll centre maximum outside diameter after the processing eventually is of a size of fit dimension with roller shell.
3, roller shell and roll centre are heat-treated respectively and fine finishining by different specification requirements after roughing.
4, roller shell after the fine finishining and roll centre make up with bonding agent, also can adopt static cooperation or other compound mode.
5, the roll after the combination is a benchmark with the roll centre shaft centre line, carries out whole processing by the process of roll.
Combined high-chromium white cast iron roll described in the utility model is compared with traditional monolithic devices roll, and the former advantage is: can be combined into best overall performance, improving roll working life, and be conducive to the production of high speed roll. Combined roll production technology described in the utility model is simple, and easy control of process conditions, and constant product quality can also be saved more valuable raw material, and especially roll centre can be reused.
Claims (2)
1, a kind of metal roll is characterized in that doing roll centre two parts that roller shell and does by spheroidal graphite cast-iron or alloy cast iron or cast steel by rich chromium cast iron for one combines.
2, metal roll according to claim 1 is characterized in that roller shell and roll centre can use adhesive bonds, and mode that also can static cooperation makes up.
