Definitions
- the invention relates to a device for tempering of metallic goods, especially for starting Tool steels after hardening, comprising an oven for Austenitizing the goods, a hardness press for the still hot Well, a tempering furnace to adjust the hardness and the Structure of the good and a promoting the good through the ovens Facility.
- a device for tempering metallic goods, in particular for tempering tool steels, comprising an oven to austenitize the goods, a hardness press for that hot goods and a tempering furnace to adjust the hardness and the structure of the good is known: ("Heat treatment of the Structural and Tool Steels ", 3rd ed., Publisher Hans Bennighoff, Sigma Book series 1978, pp. 444 to 451 and Ruhfus, "Heat Treatment of Ferrous Materials", Verlag Stahl, Eisen mbH, 1958, pp. 380 to 383 and 386).
- Air-hardening steels and tool steels are usually used tempered again after the hardening process.
- the tempering temperature is selected according to the desired final hardness. Starting serves on the one hand, setting the exact hardness and desired structure and on the other hand as a straightening process. at known methods are therefore the individual parts in Stacked between 10 to 100 pieces clamped together then left on for between three and ten hours.
- the invention aims to eliminate these disadvantages and beats starting from a device of the beginning mentioned type before that at the exit of the tempering furnace
- Cooling presses are arranged for the purpose of temperature control Cooling of the goods
- straightening presses inside the tempering furnace are arranged to the good for a certain period of time under a certain pressure and temperature to keep the goods conveying through the ovens
- Device is designed as a roller conveyor so that the Device except for the pressing and straightening processes works continuously and that the good after leaving of the tempering furnace or after leaving the cooling presses either a further processing or again to the admission of the Tempering furnace is returned.
- the actual hardening furnace is designated by 10 in the figure, it has an input area 11 and a preheating zone 12 and an austenitizing area 13. After leaving the furnace 10 the good reaches the hardness press 20, the works discontinuously. In this press is the good slowly and deliberately cooled and straightened at the same time.
- Tempering furnace 30 has a preheating stage 31 as well as a temperature maintenance level 32 and beyond still equipped with straightening presses 33 in his furnace interior. This means that the good after it is the Holding stage has happened for a corresponding period of time under a certain pressure and temperature is held in the furnace in the straightening press 33. Subsequently the material is removed from the tempering furnace 30 and can still in warm state cooling presses 40 are fed, which are in in the immediate vicinity of the outlet of the starting furnace 30 and cool the goods in a defined manner.
- the device according to the invention is one by continuous rolling conveyor provided in both furnaces, so that the Device except for the pressing and straightening processes works continuously.
- Example of production data with a device according to the invention Material 1.2003, 75 Cr1 - ⁇ 420 mm x 3.2 mm Preheating in the hardening roller furnace 10 940 ° C, 500 sec. Austenitizing in the hardening roller furnace 930 ° C, 180 sec. Quenching under the hardness press 20 70 sec, hardness 65 HRC Preheating in the starter roller furnace 30 530 ° C, 500 sec. Keep at temperature and press 550 ° C, 270 sec. Cooling under the cooling press 40 70 sec. Hardness 44 HRC
