Embodiment

[0027] Embodiment: a kind of method for hot loading of looper roll skin, comprises the following steps:

[0028] 1) Calibrate the table surface of the tooling 1 horizontally, and the roller skin passes through the limit ring 4 on the support rod 3, and is socketed on the outside of the positioning ring 2 to fix the roller skin;

[0029] 2) Use 5 crawler heaters to wrap the roller skin. The crawler heater is connected to the temperature controller. At the same time, place a thermocouple at the place where each heater contacts the roller skin. wrapped up;

[0030] 3) Set the parameters of the temperature controller. The heating process is to raise the temperature to 450°C in 30 minutes and keep it warm for 2 hours;

[0031] 4) Use the crane to lift the roller shaft, and after adjustment, ensure that the roller shaft is placed vertically;

[0032] 5) Use the inner diameter gauge to detect the inner diameter of the upper end and lower end of the roller skin to ensure that the in...

Abstract

The invention relates to the technical field of hot-charging for roll skins, and discloses a method for hot-charging for a roll skin of a loop roll. The method for hot-charging for the roll skin of the loop roll comprises the following steps: a fixture table surface is calibrated to be level, the roll skin penetrates through a limit ring on a support rod, and is connected outside a location ring in a sleeving manner and fixed, and the roll skin is wrapped through five crawler-type heaters; the crawler-type heaters are connected with a temperature controller; and meanwhile, a thermocouple is placed at a contact part of each heater and the roll skin. According to the method for hot-charging for the roll skin of the loop roll, the fixture table surface is calibrated to be level, the roll skinpenetrates through the limit ring on the support rod, and is connected outside the location ring in a sleeving manner and fixed, the roll skin is wrapped through the five crawler-type heaters, the crawler-type heaters are connected with the temperature controller, meanwhile, the thermocouple is placed at the contact part of each heater and the roll skin, and after the wrapping is completed, the heaters are wrapped through heat-insulation cotton; and the parameters of the temperature controller are set, a heating process is heating to reach 450 DEG C in 30 minutes, and insulating heat for 2 hours, accurate temperature control during hot-charging and a good hot-charging effect are achieved.

Description

technical field [0001] The invention relates to the technical field of thermal loading of roll skins, in particular to a method for thermal loading of roll skins of looper rolls. Background technique [0002] The interference fit depends on the interference value between the shaft and the hole. After assembly, elastic pressure is generated between the surfaces of the parts to obtain a tight connection. The assembly methods of interference fit mainly include press fit, heat fit and cold fit. Press-fitting refers to press-fitting at room temperature. It is suitable for several static fits with small interference. It is convenient and simple to operate, and it moves quickly. It is the most commonly used method. According to different ways of applying force, press-fitting Fitting is divided into hammering method and press-in method. The hammering method is mainly used for joints with low requirements on the mating surface and short length, and adopts a transition fit. The press-...
