There is also the control of the small particle size of sinter and coke. Some factories use graded feeding into the furnace, which reduces the return rate and saves energy and consumption

4. What's the matter with the blast furnace not being able to pressurize and release materials?

The phenomenon of sudden collapse of the furnace material when it does not drop smoothly is called material collapse. The main factors causing collapse are:

1.

Poor quality of raw fuel. Such as pipe formation or pressure differential increase.

2.

The airflow distribution is abnormal, the edge or center is too heavy, serious deflection, and pipe stroke.

3.

The thermal system fluctuates drastically or the slag alkalinity is too high.

4.

During or after tapping.

5. What are the precautions for the start-up operation of blast furnace belt-type feeding?

1 Walking on a leather belt, it is not allowed to use the belt to transport other non-raw items (including tools, spare parts, oil products, clothing, etc.); when crossing the belt, you should take a safe corridor or go around; 3. Before driving, check whether there are people in various parts or obstacles, otherwise you are not allowed to drive

.

4. When the belt conveyor slips and goes deviating, it is prohibited to use pedals, move by hand, push by people or pry with sticks

, etc. The machine should be stopped for processing. When electrical equipment fails, you should contact an electrician to deal with it, and you are not allowed to disassemble or install it without permission;

5. The integrity of the safety protection facilities should be checked frequently, and no one is allowed to change the status without permission. When cleaning, you must concentrate on preventing accidentally putting tools, sundries, and clothes into the rotating parts. If a similar situation occurs, you should immediately let go or decisively take off the clothes, cut them off, and stop the machine; you must stop the machine when cleaning the lower part of the belt. , it is strictly forbidden to handle it directly with hands when the roller is glued;

6. Platform guardrails, ladder handrails, roller protective covers, and safety emergency lighting should be inspected frequently. If there is any damage, report it for repair immediately and take temporary remedial measures. Okay

6. Where is the card slot on the computer?

Because wwan cards have two specifications, one is mini PCI-E and the other is m2, or ngff.

It’s easy to tell by appearance (find more common WiFi cards here):

The mini PCI-E has two screw holes, on both corners.

The screw hole of M2 is half, in the middle.

mini PCI-E and mSATA are physically compatible, so the wwan card slot of some notebooks can be installed with mSATA solid state, such as ThinkPad T430. But the premise is that the manufacturer has connected this interface to the motherboard's SATA interface, otherwise it will not be recognized even if the mSATA solid state is plugged in.

Pure mini PCI-E solid-state ones are actually available, but I can’t seem to find them for sale now. Someone has posted an article before:

Roison An: A rare SSD with Mini PCIe interface (not msata), it comes with Option ROM and can start the system normally

7. How to adjust the machine head on the automatic trough?

The non-adjustable wire covering machine head consists of a machine head shell, a front cover, a back cover, an inner mold, an outer mold, a mold core, and a wiring sleeve. The inner mold and the outer mold of the machine head have a fixed coaxial position structure. The inner cavity of the front cover has evenly distributed through-grooves, so that the wire coating is concentric, the thickness is uniform, the appearance is glossy and the quality is good, and the operation does not need to be adjusted. It is suitable for large quantities. Wire production, and can be matched with various types of rubber and plastic extruders at home and abroad, and has a dedicated waste removal machine

8. How does the blast furnace hoist loading frequency converter accelerate?

Common winch loading has two motors with a wire rope drum, and two frequency converters with one motor each. The frequency converter has a master-slave relationship. The master frequency converter operates at several preset frequencies controlled by switching values. Once the start signal is given, the main frequency converter accelerates to the set frequency according to the set acceleration curve acceleration time, etc.; the slave frequency converter operates in forward and reverse directions. The rotation is controlled by the switching value, while the speed is controlled by the main inverter. During the operation, the analog output port of the main inverter outputs constant analog signals to the slave inverter to achieve synchronization and evenly share the load. 9.
