Problems solved by technology

There are two important process parameters in the heat treatment process, heating temperature and time control. At present, the heating temperature system adopts a sophisticated automatic control system, and the timing confirmation control of the process is relatively simple and primitive, and it is highly dependent on people. The good and the bad happen from time to time

Embodiment Construction

[0024] Depend on figure 1 It can be known from the illustrated embodiment that it includes an AC / DC power supply DC1, a first contactor to a seventh contactor, a first time relay to a fifth time relay, a double-pole double-throw power switch, a manual switch K1~K3, and an indicator light. D1~D4, alarm light D5 and alarm horn H;

[0025] The static contacts of the first contact K0-1 and the second contact K0-2 of the double-pole double-throw power switch are respectively connected to both ends of the AC 220V power supply; the alarm light D5 and the alarm horn H are connected in parallel and then connected to the The first normally open contact T4-1 of the fourth contactor is connected in series to form an alarm circuit, and the alarm circuit is connected to the boom and the second contact of the first contact K0-1 of the double-pole double-throw power switch. Between the booms of K0-2;

[0026] The input ends of the AC / DC power supply DC1 are respectively connected to the boo...

Abstract

The invention discloses a thermal treatment process timed prompting and alarming device, which comprises an AC / DC power supply DC1, contactors from the first to the seventh, time relays from the first to the fifth, a double-pole double-throw power switch, a manual switch K1, a manual switch K2, a manual switch K3, indicating lamps from D1 to D4, an alarming lamp D5 and an alarming loudspeaker H. The thermal treatment process timed prompting and alarming device has the beneficial effects that: the device can prompt the operator to carry out process confirmation at regular intervals, solves the problems of instability and randomness of working parameter data acquisition during the thermal treatment production process, has obvious stable processing capability, and prevents falsification. The thermal treatment process timed prompting and alarming device has the functions of manual / automatic starting, sound-light alarming, prompting alarming of timed prompting on operator to carry out process confirmation, thermal treatment completion prompting alarming, water level abnormity alarming, furnace door abnormity alarming, calculation of duration that the operator fails to operate as required, and manual misoperation prevention. The thermal treatment process timed prompting and alarming device has the advantages of simple structure, convenient operation, good expansibility and convenient manufacturing, installation and maintenance.

Description

technical field [0001] The invention belongs to the technical field of heat treatment process timing confirmation, and relates to a heat treatment process timing prompt and alarm device. Background technique [0002] Heat treatment of metal products is an important process to change the mechanical, physical and chemical properties of materials to obtain different performance. There are two important process parameters in the heat treatment process, heating temperature and time control. At present, the heating temperature system adopts a precise automatic control system, and the timing confirmation control of the process is relatively simple and primitive, and it is highly dependent on people, and human errors lead to products. The good and the bad happen from time to time. How to make the confirmation of the heat treatment process more precise has become an important problem to be solved at present. SUMMARY OF THE INVENTION [0003] The technical problem to be solved by ...
