Automatic control systems are widely used in various fields, especially in industrial fields, and temperature control is one of the most common control types in control systems. With the rapid development of single-chip microcomputer technology, controlling the controlled object through single-chip microcomputer has increasingly become an important development direction in the field of automatic control in the future. This design requires the design of an electric furnace temperature control system with a single-chip microcomputer.X3.5 BENCH MILL DRILL The temperature control system is mainly composed of four parts: temperature sensor, temperature regulator, actuator, and controlled object. Its system structure diagram. The controlled object is a large-capacity, large-inertia electric furnace temperature object, which is a typical multi-order volume delay characteristic. In engineering, it is often approximated as a second-order volume delay with pure hysteresis; due to the large capacitance of the controlled object, SCR is usually used as the actuator of the regulator.SX3-DIGI SMALL MILL DRILL To adjust the temperature of the heating furnace, in the industry, within the set cycle range, the circuit is turned on for several cycles, and then several cycles are turned off, and the ratio of the on-off time of the thyristor in the set cycle is changed to adjust the load. The average voltage of the terminal AC is the load power, which is commonly referred to as a power regulator or a cycle controller; How to Update your heat treatment The power regulator triggers the thyristor to turn on when the power supply voltage crosses zero, so what is obtained on the load is a complete sine wave, and what is adjusted is only the voltage cycle that is turned on within the set period Tc. Assuming that the wave number of the conduction cycle in the cycle Tc is n, and the cycle of each cycle is T, then the output power of the power regulator is P=n×T×Pn/Tc, and Pn is when the voltage in the set cycle Tc is fully passed The output power of the device.Vacuum heat treatment process of TC11 titanium alloy pipe

The CPHT is about having a blast on the ice with our friends and other hockey lovers. But... sometimes you just can't pull those friends away from the real world. So we've created this forum for you to find other 'Pond-minded' hockey players so that you can form a team!
​
Whether you're looking to build a team from scratch, just one player, or a team to coach... We bet that after a game on the pond and a cold brewski, you'll have a handful of new best friends.
