It's a hot summer, and the heat is unbearable
The utilization rate of refrigeration equipment has increased significantly
The demand for thermal coal is increasing everywhere
A 10,000-ton "dragon" on the Daqin Railway
Send "coolness" to thousands of households
There are many curves and long ramps on the Daqin Railway
It is very important that the train has a good braking system
The brake shoe is a key component in the train braking system
It's like a bike's brake pads
By directly rubbing the train wheels
Slow down and stop the train
Its reliability is directly related to the safety of driving
There are many types of brake shoes
Among them, synthetic brake shoes are mainly used for:
Braking of railway wagons
Including braking for heavy-haul trains on the Daqin Railway
If you want to control this 10,000-ton "dragon"
There is no "real kung fu"
It's really hard to do
How did it "cultivate"?
01
"Transform"
When it was still an iron plate
It is fed into the stamping and forming area
After five stamping and forming
and a deburring "plastic surgery"
Its basic appearance was created
At this time, call it a tile back
02
Initial forming
10 kinds of materials such as rubber and filler
After mixing and crushing
By a certain weight
with a tile back coated with adhesive
Put them together in a hydraulic press for hot press molding
After high-temperature compression
Preliminary formation of synthetic brake shoes
03
The Ultimate "Cultivation"
After that, the composite brake shoe will be preliminarily formed
Place in a curing oven
In a stepwise ramp-up to 155°C
Curing for 13 hours
High coefficient of friction synthetic brake shoes
In the end, the "cultivation" was successful
High coefficient of friction synthetic brake shoes
It has the characteristics of high wear resistance and long service life
It is also more adaptable to train wheels
under extreme environmental conditions
It has good brake friction performance
Shanxi Railway Equipment Manufacturing Group Locomotive and Rolling Stock Co., Ltd., as the largest enterprise in the production of high friction coefficient synthetic brake shoes for railway wagons in China, sells and supplies 11 railway bureau group companies such as Taiyuan Bureau Group Company, with an annual supply of 1.8 million pieces, and the production task is very arduous.
In the production of synthetic brake shoes with a high coefficient of friction
The masters have to add day and night
Non-stop shifts
Complete the task with quality and quantity
"The production process of high-friction synthetic brake shoes requires a high temperature environment, and on a hot summer day, the temperature next to the station is close to 40°C, and we are like a 'sauna', and the sweat basically does not stop. However, the employees have not lowered their standards because of this, and it is our duty and mission to ensure that the production of each piece of high friction coefficient synthetic brake shoe is qualified. Fu Linsheng, director of the synthetic tile workshop, said.
After the masters checked at all levels
"Cultivated" into a high coefficient of friction synthetic brake shoe
Quality clearance
For the 10,000-ton "dragon" galloping
