The May Day holiday is one of the long holidays in our country. Have you ever wondered about the origin and origin of this festival? Today let’s trace the history of this holiday.
In the 1880s, as capitalism entered the monopoly stage, the ranks of the American proletariat grew rapidly, and a magnificent labor movement emerged. At that time, the American bourgeoisie brutally exploited and squeezed the working class in order to accumulate capital. They used various means to force workers to work for up to 12 to 16 hours a day. The vast majority of workers in the United States have gradually realized that in order to protect their rights, they must rise up and fight.
Beginning in 1884, advanced workers' organizations in the United States passed resolutions to fight for the realization of an "eight-hour work day" and decided to launch an extensive struggle to implement the eight-hour work day on May 1, 1886. After the slogan of the eight-hour working day was put forward, it immediately received enthusiastic support and response from the working class across the United States. Thousands of workers in many cities joined this struggle. The striking workers were brutally suppressed by the U.S. authorities, and many workers were killed and arrested.
On May 1, 1886, 350,000 workers in Chicago and other cities in the United States held general strikes and demonstrations, demanding the implementation of an eight-hour work system and improvement of working conditions. The struggle shook the entire United States. The powerful force of the working class's united struggle forced the capitalists to accept the workers' demands. The general strike by American workers was victorious.
In July 1889, the Second International led by Engels held a congress in Paris. In order to commemorate the "May Day" strike of American workers, demonstrate the great power of "Workers of the world, unite!" and promote the struggle of workers in various countries for an eight-hour working day, the meeting passed a resolution stipulating that May 1, 1890 International workers held a demonstration and decided to designate May 1 as International Labor Day.
Every time the finishing tube is rolled, it must go through the process of solution treatment. Ta ensure that the performance of the steel pipe meets the technical requirements. and to provide guarantee for the post-process processing or use. Bright solution treatment process of ultra-long seamless steel pipe has always been a difficulty in the industry.
Traditional electric furnace equipment is large,covers a large area, has high energy consumption and large gas consumption, so it is difficult for realize bright solution process. After years of hard work and innovative development, the use of current advanced induction heating technology and DSP power supply. Precision control of heating temperature to ensure that the temperature is controlled within t2C,to solve the technical problem of inaccurate induction heating temperature control. The heated steel pipe is cooled by "heat conduction"in a special closed cooling tunnel, which greatly reduces the gas consumption and is more environmentally friendly.
